Phone Overview

The Cisco Unified IP Phone 7975G, 7971G-GE (gigabit Ethernet version), 7970G, 7965G, and 7945G is a full-featured telephone that provides voice communication over an Internet Protocol (IP) network. These IP phones function much like digital business phones and allow you to place and receive phone calls and to access features such as mute, hold, transfer, speed dial, call forward, and more. In addition, because Cisco Unified IP Phones connect to your data network, they offer enhanced IP telephony features, such as access to network information and services and customizable features and services. The phones also support security features that include file authentication, device authentication, signaling encryption, and media encryption.

The Cisco Unified IP Phone 7975G, 7971G-GE, 7970G, 7965G, and 7945G provides a color screen (touchscreen for the 7975G, 7971G-GE, and the 7970G), support for line or speed dial numbers, context-sensitive online help for buttons and features, and a variety of other sophisticated functions.

A Cisco Unified IP Phone, like other network devices, must be configured and managed. These phones encode G.711a, G.711mu, G.722, G.729a, G.729ab, iLBC, and decode G.711a, G.711mu, G.722, G.729, G729a, G.729b, G.729ab, and iLBC. These phones also support uncompressed wideband (16 bits, 16 kHz) audio.

Caution

Use of a cell, mobile, or GSM phone or two-way radio in close proximity to a Cisco Unified IP Phone might cause interference. For more information, see the manufacturer documentation of the interfering device.

Network Protocols

Cisco Unified IP Phones support several industry-standard and Cisco network protocols that are required for voice communication. The following table provides an overview of the network protocols that the Cisco Unified IP Phone 7975G, 7971G-GE, 7970G, 7965G, and 7945G supports.

Supported Network Protocols on the Cisco Unified IP Phone

Network protocol

Purpose

Usage notes

Bootstrap Protocol (BootP)

BootP enables a network device such as the Cisco Unified IP Phone to discover certain startup information, such as its IP address.

If you are using BootP to assign IP addresses to the Cisco Unified IP Phone, the BOOTP Server option shows "Yes" in the network configuration settings on the phone.

Cisco Discovery Protocol (CDP)

CDP is a device-discovery protocol that runs on all Cisco-manufactured equipment.

By using CDP, a device can advertise its existence to other devices and receive information about other devices in the network.

The Cisco Unified IP Phone uses CDP to communicate information such as auxiliary VLAN ID, per port power management details, and Quality of Service (QoS) configuration information with the Cisco Catalyst switch.

Cisco Peer-to-Peer Distribution Protocol (CPPDP)

CPPDP is a Cisco proprietary protocol that forms a-peer-to-peer hierarchy of devices. CPPDP also copies firmware or other files from peer devices to neighboring devices.

The Peer Firmware Sharing feature uses CPPDP.

Dynamic Host Configuration Protocol (DHCP)

DHCP dynamically allocates and assigns an IP address to network devices.

DHCP enables you to connect an IP phone into the network and have the phone become operational without the need to assign an IP address manually or to configure additional network parameters.

DHCP is enabled by default. If disabled, you must manually configure the IP address, subnet mask, gateway, and a TFTP server on each phone locally.

Cisco recommends that you use DHCP custom option 150. With this method, you configure the TFTP server IP address as the option value. For additional supported DHCP configurations, see the "Dynamic Host Configuration Protocol" and "Cisco TFTP" chapters in the Cisco Unified Communications Manager System Guide.

Hypertext Transfer Protocol (HTTP)

HTTP is the standard way of transferring information and moving documents across the Internet and the web.

Cisco Unified IP Phones use HTTP for XML services and for troubleshooting purposes. The phones use HTTP to download configuration files and firmware loads. If the HTTP download fails, the phone uses TFTP to transfer the files.

Cisco Unified IP Phones do not support the use of IPv6 addresses in the URL. You cannot use a literal IPv6 address in the URL or a hostname that maps to an IPv6 address.

Hypertext Transfer Protocol Secure (HTTPS)

Hypertext Transfer Protocol Secure (HTTPS) is a combination of the Hypertext Transfer Protocol with the SSL/TLS protocol to provide encryption and secure identification of servers.

Web applications with both HTTP and HTTPS support have two URLs configured. For a Cisco Unified IP Phone that supports HTTPS, choose the HTTPS URL from the two URLs.

IEEE 802.1X

The IEEE 802.1X standard defines a client-server-based access control and authentication protocol that restricts unauthorized clients from connecting to a LAN through publicly accessible ports.

Until the client authenticates, 802.1X access control allows only Extensible Authentication Protocol over LAN (EAPOL) traffic through the port to which the client connects. After authentication is successful, normal traffic can pass through the port.

The Cisco Unified IP Phone implements the IEEE 802.1X standard by supporting the following authentication methods: EAP-FAST, EAP-TLS, and EAP-MD5.

When 802.1X authentication is enabled on the phone, you should disable the PC port and voice VLAN. See 802.1X Authentication for additional information.

Internet Protocol (IP)

IP is a messaging protocol that addresses and sends packets across the network.

To communicate by using IP, network devices must have an assigned IP address, subnet, and gateway.

IP addresses, subnets, and gateways identifications are automatically assigned if you use the Cisco Unified IP Phone with Dynamic Host Configuration Protocol (DHCP). If you do not use DHCP, you must manually assign these properties to each phone locally.

The Cisco Unified IP Phone supports concurrent IPv4 and IPv6 addresses. Configure the IP addressing mode (IPv4 only, IPv6 only, or both IPv4 and IPv6) in Cisco Unified Communications Manager Administration. For more information, see the "Internet Protocol Version 6 (IPv6)" chapter in the Cisco Unified Communications Manager Features and Services Guide.

Link Layer Discovery Protocol (LLDP)

LLDP is a standardized network discovery protocol (similar to CDP) that some Cisco and third-party devices support.

The Cisco Unified IP Phone supports LLDP on the PC port.

Link Layer Discovery Protocol-Media Endpoint Devices (LLDP-MED)

LLDP-MED is an extension of the LLDP standard developed for voice products.

The Cisco Unified IP Phone supports LLDP-MED on the SW port to communicate information such as:

- Voice VLAN configuration

- Device discovery

- Power management

- Inventory management

For more information about LLDP-MED support, see the LLDP-MED and Cisco Discovery Protocol white paper:

http://www.cisco.com/en/US/tech/tk652/tk701/technologies_white_paper0900aecd804cd46d.shtml

Real-Time Control Protocol (RTCP)

RTCP works with Real-Time Transport Protocol (RTP) to provide QoS data (such as jitter, latency, and round trip delay) on RTP streams.

RTCP is disabled by default, but you can enable it on a per-phone basis in Cisco Unified Communications Manager Administration. For more information, see Network Configuration Menu.

Real-Time Transport Protocol (RTP)

RTP is a standard protocol for transport of real-time data, such as interactive voice and video, over data networks.

Cisco Unified IP Phones use the RTP protocol to send and receive real-time voice traffic from other phones and gateways.

Session Initiation Protocol (SIP)

SIP is the Internet Engineering Task Force (IETF) standard for multimedia conferencing over IP. SIP is an ASCII-based application-layer control protocol (defined in RFC 3261) that can establish, maintain, and terminate calls between two or more endpoints.

Like other VoIP protocols, SIP addresses the functions of signaling and session management within a packet telephony network. Signaling allows call information to be carried across network boundaries. Session management provides the ability to control the attributes of an end-to-end call.

You can configure the Cisco Unified IP Phone to use either SIP or Skinny Client Control Protocol (SCCP).

Cisco Unified IP Phones do not support the SIP protocol when the phones operate in IPv6 address mode.

Skinny Client Control Protocol (SCCP)

SCCP includes a messaging set that allows communications between call control servers and endpoint clients such as IP Phones. SCCP is proprietary to Cisco Systems.

Cisco Unified IP Phones use SCCP for call control. You can configure the Cisco Unified IP Phone to use either SCCP or Session Initiation Protocol (SIP).

Session Description Protocol (SDP)

SDP is the portion of the SIP protocol that determines which parameters are available during a connection between two endpoints. Conferences are established by using only the SDP capabilities that all endpoints in the conference support.

SDP capabilities, such as codec types, DTMF detection, and comfort noise, are normally configured on a global basis by Cisco Unified Communications Manager or Media Gateway in operation. Some SIP endpoints may allow configuration of these parameters on the endpoint itself.

Transmission Control Protocol (TCP)

TCP is a connection-oriented transport protocol.

Cisco Unified IP Phones use TCP to connect to Cisco Unified Communications Manager and to access XML services.

Transport Layer Security (TLS)

TLS is a standard protocol for securing and authenticating communications.

When security is implemented, Cisco Unified IP Phones use the TLS protocol for secure registration with Cisco Unified Communications Manager.

For more information, see the Cisco Unified Communications Manager Security Guide.

Trivial File Transfer Protocol (TFTP)

TFTP allows you to transfer files over the network.

On the Cisco Unified IP Phone, TFTP enables you to obtain a configuration file that is specific to the phone type.

TFTP requires a TFTP server in your network, which can be automatically identified from the DHCP server. If you want a phone to use a TFTP server other than the one that the DHCP server specifies, you must manually assign TFTP server from the Network Configuration menu on the phone.

For more information, see the "Cisco TFTP" chapter in the Cisco Unified Communications Manager System Guide.

User Datagram Protocol (UDP)

UDP is a connectionless messaging protocol for delivery of data packets.

Cisco Unified IP Phones transmit and receive RTP streams, which utilize UDP.

- IPv6 Support on Cisco Unified IP Phones

IPv6 Support on Cisco Unified IP Phones

The Cisco Unified IP Phones use the Internet Protocol to provide voice communication over the network. Because Internet Protocol version 4 (IPv4) uses a 32-bit address, it cannot meet the increased demands for unique IP addresses for all devices that connect to the internet. Therefore, Internet Protocol version 6 (IPv6) is an updated version of the current Internet Protocol. IPv6 uses a 128-bit address and provides end-to-end security capabilities, enhanced Quality of Service (QoS), and increased number of available IP addresses.

The Cisco Unified IP Phone supports IPv4-only addressing mode, IPv6-only addressing mode, as well as an IPv4/IPv6 dual stack addressing mode. In IPv4, you can enter each octet of the IP address on the phone in dotted decimal notation; for example, 192.240.22.5. In IPv6, you can enter each octet of the IP address in hexadecimal notation with each octet separated by a colon; for example, 2005:db8:0:1:ef8:9876:ba72:dc9a. The phone truncates and removes leading zeros when it displays the IPv6 address.

Cisco Unified IP Phones support both IPv4 and IPv6 addresses transparently, so users can handle all calls on the phone to which they are accustomed. Cisco Unified IP Phones with the Skinny Call Control Protocol (SCCP) support IPv6. Cisco Unified IP Phones with SIP do not support IPv6.

Cisco Unified IP Phones do not support URLs with IPv6 addresses in the URL. This affects all IP Phone Service URLs, such as services, directories, messages, help, and any restricted web services that require the phone to use the HTTP protocol to validate credentials with the Authentication URL. If you configure Cisco Unified IP Phone services for Cisco Unified IP Phones, you must configure the phone and the servers that support the phone service with IPv4 addresses.

If you configure IPv6 Only as the IP Addressing Mode for phones that are running SIP, the Cisco TFTP service overrides the IP Addressing Mode configuration and uses IPv4 Only in the configuration file.

For more information on IPv6 deployment in your Cisco Unified Communications network, see the "Internet Protocol Version 6 (IPv6)" chapter in the Cisco Unified Communications Manager Features and Services Guide and Deploying IPv6 in Unified Communications Networks with Cisco Unified Communications Manager, located at http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/srnd/ipv6/ipv6srnd.html.

Cisco Unified IP Phone 7975G, 7971G-GE, 7970G, 7965G, and 7945G Supported Features

The Cisco Unified IP Phone functions much like a digital business phone and allows you to place and receive telephone calls. In addition to traditional telephony features, the Cisco Unified IP Phone includes features that enable you to administer and monitor the phone as a network device.

This section includes the following topics:

- Feature Overview

- Telephony Feature Administration

- Cisco Unified IP Phone Network Parameters

- Information for End Users

Feature Overview

Cisco Unified IP Phones provide traditional telephony functionality, such as call forwarding and transferring, redialing, speed dialing, conference calling, and voice messaging system access. Cisco Unified IP Phones also provide a variety of other features.

As with other network devices, you must configure Cisco Unified IP Phones to prepare them to access Cisco Unified Communications Manager and the rest of the IP network. By using DHCP, you have fewer settings to configure on a phone, but if your network requires it, you can manually configure an IP address, TFTP server, subnet information, and other values.

The Cisco Unified IP Phone interacts with other services and devices on your IP network to provide enhanced functionality. For example, you can integrate the Cisco Unified IP Phones with the corporate Lightweight Directory Access Protocol 3 (LDAP3) standard directory to enable users to search for coworker contact information directly from their IP phones. You can also use XML to enable users to access information such as weather, stocks, quote of the day, and other web-based information.

Finally, because the Cisco Unified IP Phone is a network device, you can obtain detailed status information from it directly. This information can assist you with troubleshooting any problems that users encounter when they use their IP phones.

Cisco Unified IP Phone Security Features

Implementation of security in the Cisco Unified Communications Manager system prevents identity theft of the phone and Cisco Unified Communications Manager server, prevents data tampering, and prevents call signaling and media stream tampering.

To alleviate these threats, the Cisco Unified IP telephony network establishes and maintains authenticated and encrypted communication streams between a phone and the server, digitally signs files before they are transferred to a phone, and encrypts media streams and call signaling between Cisco Unified IP phones.

The Cisco Unified IP Phone 7975G, 7971G-GE, 7970G, 7965G, and 7945G uses the Phone Security Profile, which defines whether the device is nonsecure, authenticated, or encrypted. For information on application of the security profile to the phone, see the Cisco Unified Communications Manager Security Guide.

If you configure security-related settings in Cisco Unified Communications Manager Administration, the phone configuration file will contain sensitive information. To ensure the privacy of a configuration file, you must configure it for encryption. For detailed information, see the "Configuring Encrypted Phone Configuration Files" chapter in the Cisco Unified Communications Manager Security Guide.

The following table shows where you can find additional information about security in this and other documents.

Overview of security features

Feature

Description

Image authentication

Signed binary files (with the extension .sbn) prevent tampering with the firmware image before it loads on a phone. Tampering with the image causes a phone to fail the authentication process and reject the new image.

Customer-site certificate installation

Each Cisco Unified IP Phone requires a unique certificate for device authentication. Phones include a manufacturing installed certificate (MIC), but for additional security, you can specify in Cisco Unified Communications Manager Administration that a certificate be installed by using the CAPF (Certificate Authority Proxy Function). Alternatively, you can install a Locally Significant Certificate (LSC) from the Security Configuration menu on the phone.

Device authentication

Occurs between the Cisco Unified Communications Manager server and the phone when each entity accepts the certificate of the other entity. Determines whether a secure connection between the phone and a Cisco Unified Communications Manager should occur, and, if necessary, creates a secure signaling path between the entities that use TLS protocol. Cisco Unified Communications Manager does not register phones unless it can authenticate them.

File authentication

Validates digitally signed files that the phone downloads. The phone validates the signature to make sure that file tampering did not occur after file creation. Files that fail authentication are not written to Flash memory on the phone. The phone rejects such files without further processing.

Signaling authentication

Uses the TLS protocol to validate that no tampering has occurred to signaling packets during transmission.

Manufacturing installed certificate

Each Cisco Unified IP Phone contains a unique manufacturing installed certificate (MIC), which is used for device authentication. The MIC is a permanent unique proof of identity for the phone, and allows Cisco Unified Communications Manager to authenticate the phone.

Secure SRST reference

After you configure an SRST reference for security and then reset the dependent devices in Cisco Unified Communications Manager Administration, the TFTP server adds the SRST certificate to the phone cnf.xml file and sends the file to the phone. A secure phone then uses a TLS connection to interact with the SRST-enabled router.

Media encryption

Uses Secure Real-time Transport Protocol (SRTP ) to ensure that the media streams between supported devices prove secure and that only the intended device receives and reads the data. Includes creation of a media primary key pair for the devices, delivery of the keys to the devices, and securing the key delivery while the keys are in transport.

Signaling encryption

Ensures that all SCCP and SIP signaling messages that are sent between the device and the Cisco Unified Communications Manager server are encrypted.

CAPF (Certificate Authority Proxy Function)

Implements parts of the certificate generation procedure that are too processing-intensive for the phone, and interacts with the phone for key generation and certificate installation. The CAPF can be configured to request certificates from customer-specified certificate authorities on behalf of the phone, or it can be configured to generate certificates locally.

Security profiles

Defines whether the phone is nonsecure, authenticated, encrypted, or protected.

Encrypted configuration files

Ensures the privacy of phone configuration files.

Optional disabling of the web server functionality for a phone

Prevents access to a phone web page, which displays a variety of operational statistics for the phone.

Phone hardening

Additional security options, which you control from Cisco Unified Communications Manager Administration:

- Disabling PC port

- Disabling Gratuitous ARP (GARP)

- Disabling PC Voice VLAN access

- Disabling access to the Setting menus, or providing restricted access that allows access to the User Preferences menu and saving volume changes only

- Disabling access to web pages for a phone

Note

View current settings for the PC Port Disabled, GARP Enabled, and Voice VLAN enabled options by looking at the phone Security Configuration menu.

802.1X Authentication

The Cisco Unified IP Phone can use 802.1X authentication to request and gain access to the network.

Authenticated, Encrypted, and Protected Phone Calls

When security is implemented for a phone, you can identify authenticated or encrypted phone calls by icons on the phone screen. You can also determine whether the connected phone is secure and protected if a security tone plays at the beginning of the call.

In an authenticated call, all devices that participate in the establishment of the call are trusted devices that Cisco Unified Communications Manager authenticates. When a call in progress is authenticated, the call progress icon to the right of the call duration timer in the phone screen changes to this icon: .

In an encrypted call, all devices that participate in the establishment of the call are trusted devices that Cisco Unified Communications Manager authenticates. In addition, call signaling and media streams are encrypted. An encrypted call offers a high level of security and provides integrity and privacy to the call. When a call in progress is encrypted, the call progress icon to the right of the call duration timer in the phone screen changes to this icon: .

Note

If the call routes through non-IP call legs, for example, PSTN (public switched telephone network), the call may be nonsecure even though it is encrypted within the IP network and has a lock icon associated with it.

In a protected call, a security tone plays at the beginning of a call to indicate that the other connected phone is also receiving and transmitting encrypted audio and video (if video is involved). If your call connects to a non-protected phone, the security tone does not play.

Note

Protected calling is supported for connections between two phones only. Some features, such as conference calling, shared lines, Extension Mobility, and Join Across Lines are not available when protected calling is configured. Protected calls are not authenticated.

Secure Conference Call Identification

You can initiate a secure conference call and monitor the security level of participants. Establishment of a secure conference call follows this process:

1. A user initiates the conference from a secure phone (encrypted or authenticated security mode).

2. Cisco Unified Communications Manager assigns a secure conference bridge to the call.

3. As participants are added, Cisco Unified Communications Manager verifies the security mode of each phone (encrypted or authenticated) and maintains the secure level for the conference.

4. The phone displays the security level of the conference call. A secure conference displays (encrypted) or (authenticated) icon to the right of “Conference” on the phone screen. If icon displays, the conference is not secure.

Note

Certain interactions, restrictions, and limitations affect the security level of the conference call. These interactions depend on the security mode of the participant phones and the availability of secure conference bridges. See Call Security Interactions and Restrictions for information about these interactions.

Protected Call Identification

A protected call is established when a user phone and the phone on the other end are configured for protected calling. The other phone can be in the same Cisco IP network, or on a network outside the IP network. Protected calls can only be made between two phones. Conference calls and other multiple-line calls are not supported.

Establishment of a protected call follows this process:

1. A user initiates the call from a protected phone (protected security mode).

2. The phone displays the icon (encrypted) on the phone screen. This icon indicates that the phone is configured for secure (encrypted) calls, but this does not mean that the other connected phone is also protected.

3. A security tone plays if the call connects to another protected phone; the tone indicates that both ends of the conversation are encrypted and protected. If the call is connected to a nonprotected phone, the secure tone does not play.

Note

Protected calling is supported for conversations between two phones. Some features, such as conference, shared lines, Cisco Extension Mobility, and Join Across Lines are not available when protected calling is configured.

Call Security Interactions and Restrictions

Cisco Unified Communications Manager checks the phone security status when conferences are established and changes the security indication for the conference or blocks the completion of the call to maintain integrity and also security in the system. The following table provides information about changes to call security levels when the Barge feature is used.

802.1X Authentication

These sections provide information about 802.1X support on the Cisco Unified IP Phones:

- Overview

- Required Network Components

- Best-Practice Requirements and Recommendations

Overview

Cisco Unified IP Phones and Cisco Catalyst switches traditionally use Cisco Discovery Protocol (CDP) to identify each other and determine parameters such as VLAN allocation and inline power requirements. CDP does not identify locally attached workstations. Cisco Unified IP Phones provide an EAPOL pass-through mechanism. This mechanism allows a workstation attached to the Cisco Unified IP Phone to pass EAPOL messages to the 802.1X authenticator at the LAN switch. The pass-through mechanism ensures that the IP phone does not act as the LAN switch to authenticate a data endpoint before accessing the network.

Cisco Unified IP Phones also provide a proxy EAPOL Logoff mechanism. In the event that the locally attached PC disconnects from the IP phone, the LAN switch does not see the physical link fail, because the link between the LAN switch and the IP phone is maintained. To avoid compromising network integrity, the IP phone sends an EAPOL-Logoff message to the switch on behalf of the downstream PC, which triggers the LAN switch to clear the authentication entry for the downstream PC.

Cisco Unified IP Phones also contain an 802.1X supplicant. This supplicant allows network administrators to control the connectivity of IP phones to the LAN switch ports. The current release of the phone 802.1X supplicant uses the EAP-FAST, EAP-TLS, and EAP-MD5 options for network authentication.

Required Network Components

Support for 802.1X authentication on Cisco Unified IP Phones requires several components, including:

- Cisco Unified IP Phone: The phone acts as the 802.1X supplicant, which initiates the request to access the network.

- Cisco Secure Access Control Server (ACS) (or other third-party authentication server): The authentication server and the phone must both be configured with a shared secret that authenticates the phone.

- Cisco Catalyst Switch (or other third-party switch): The switch must support 802.1X, so it can act as the authenticator and pass the messages between the phone and the authentication server. After the exchange completes, the switch grants or denies the phone access to the network.

Best-Practice Requirements and Recommendations

- Enable 802.1X Authentication: If you want to use the 802.1X standard to authenticate Cisco Unified IP Phones, make sure that you have properly configured the other components before you enable the standard on the phone.

MAC Authentication Bypass (MAB) is required as a fallback to 802.1x authentication for the LSC certificate update process. Enable MAB on the phone port. For more information, see https://www.cisco.com/c/en/us/products/collateral/ios-nx-os-software/identity-based-networking-services/config_guide_c17-663759.html.

- Configure PC Port: The 802.1X standard does not take into account the use of VLANs and thus recommends that only a single device be authenticated to a specific switch port. However, some switches (such as Cisco Catalyst switches) support multidomain authentication. The switch configuration determines whether you can connect a PC to the phone PC port.

- Enabled: If you use a switch that supports multidomain authentication, you can enable the PC port and connect a PC to it. In this case, Cisco Unified IP Phones support proxy EAPOL-Logoff to monitor the authentication exchanges between the switch and the attached PC. For more information about IEEE 802.1X support on the Cisco Catalyst switches, see the Cisco Catalyst switch configuration guides at:

http://www.cisco.com/en/US/products/hw/switches/ps708/tsd_products_support_series_home.html

- Disabled: If the switch does not support multiple 802.1X-compliant devices on the same port, you should disable the PC Port when 802.1X authentication is enabled. If you do not disable this port and subsequently attempt to attach a PC to it, the switch will deny network access to the phone and the PC.

- Configure Voice VLAN: Because the 802.1X standard does not account for VLANs, you should configure this setting according to the switch support.

- Enabled: If you use a switch that supports multidomain authentication, you can continue to use the voice VLAN.

- Disabled: If the switch does not support multidomain authentication, disable the Voice VLAN and consider assigning the port to the native VLAN.

- Enter MD5 Shared Secret: If you disable 802.1X authentication or perform a factory reset on the phone, the previously configured MD5 shared secret is deleted.

Security Restrictions

A user cannot barge into an encrypted call if the phone that is used to barge is not configured for encryption. When barge fails in this case, a reorder (fast busy) tone plays on the phone of the barge initiator.

If the initiator phone is configured for encryption, the barge initiator can barge into an authenticated or nonsecure call from the encrypted phone. After the barge occurs, Cisco Unified Communications Manager classifies the call as nonsecure.

If the initiator phone is configured for encryption, the barge initiator can barge into an encrypted call, and the phone indicates that the call is encrypted.

A user can barge into an authenticated call, even if the phone that is used to barge is nonsecure. The authentication icon continues to appear on the authenticated devices in the call, even if the initiator phone does not support security.

Phone Power Consumption

The Cisco Unified IP Phone 7900 Series supports Cisco EnergyWise. EnergyWise is also known as Power Save Plus. When your network contains an EnergyWise controller, you can configure these phones to sleep (power down) and wake (power up) on a schedule to reduce your power consumption. The phone should be powered by the Power Over Ethernet (PoE) port of the switch instead of the power adapter.

You set up each phone to enable or disable the EnergyWise settings. You can also configure EnergyWise parameters on the enterprise and common phone configuration. If EnergyWise is enabled, you configure a sleep and wake time, as well as other parameters. These parameters are sent to the phone as part of the phone configuration XML file.

The switch administrator can wake the phone up before the scheduled time. For more information on powering up the phones from the switch, see the switch documentation.

Cisco Unified IP Phone Deployment

Upon deployment of a new IP telephony system, system administrators and network administrators must complete several initial configuration tasks to prepare the network for IP telephony service. For information and a checklist for setup and configuration of a Cisco Unified IP telephony network, see the "System Configuration Overview" chapter in the Cisco Unified Communications Manager System Guide.

After you have set up the IP telephony system and configured system-wide features in Cisco Unified Communications Manager, you can add IP phones to the system.

Phone and Telephony Network Overview

Cisco Unified IP Phones enable you to communicate by using voice over a data network. To provide this capability, the IP phones depend upon and interact with several other key Cisco Unified IP Telephony and network components, including Cisco Unified Communications Manager, DNS and DHCP servers, TFTP servers, media resources, Cisco PoE, and others.

This chapter focuses on the interactions between the Cisco Unified IP Phone 7975G, 7971G-GE, 7970G, 7965G, and 7945G and Cisco Unified Communications Manager, DNS and DHCP servers, TFTP servers, and switches. It also describes options for powering phones.

For related information about voice and IP communications, see this URL:

http://www.cisco.com/en/US/products/sw/voicesw/index.html

This chapter provides an overview of the interaction between the Cisco Unified IP Phone and other key components of the Voice over IP (VoIP) network.

Cisco Unified IP Communications Product Interactions

To function in the IP telephony network, the Cisco Unified IP Phone must be connected to a networking device, such as a Cisco Catalyst switch. You must also register the Cisco Unified IP Phone with a Cisco Unified Communications Manager system before the phone can send and receive calls.

This section includes these topics:

- Cisco Unified IP Phone and Cisco Unified Communications Manager Interactions

- Cisco Unified IP Phone and VLAN Interaction

Cisco Unified IP Phone and Cisco Unified Communications Manager Interactions

Cisco Unified Communications Manager is an open and industry-standard call processing system. Cisco Unified Communications Manager software sets up and tears down calls between phones, thus integrating traditional PBX functionality with the corporate IP network. Cisco Unified Communications Manager manages the components of the IP telephony system—the phones, the access gateways, and the resources necessary for features such as call conferencing and route planning. Cisco Unified Communications Manager also provides:

- Firmware for phones

- Authentication and encryption (if configured for the telephony system)

- Configuration, CTL, and Identity Trust List (ITL) files via the TFTP service

- Phone registration

- Call preservation, so that a media session continues if signaling is lost between the primary Communications Manager and a phone

For information about configuring Cisco Unified Communications Manager to work with the IP devices described in this chapter, see the Cisco Unified Communications Manager Administration Guide, the Cisco Unified Communications Manager System Guide, and the Cisco Unified Communications Manager Security Guide.

Note

If the Cisco Unified IP Phone model that you want to configure does not appear in the Phone Type drop-down list in Cisco Unified Communications Manager Administration, go to the following URL and install the latest support patch for your version of Cisco Unified Communications Manager:

http://www.cisco.com/kobayashi/sw-center/sw-voice.shtml

Cisco Unified IP Phone and VLAN Interaction

The Cisco Unified IP Phone 7975G, 7971G-GE, 7970G, 7965G, and 7945G have an internal Ethernet switch, which enables forwarding of packets to the phone and to the access port and the network port on the back of the phone.

If a computer is connected to the access port, the computer and the phone share the same physical link to the switch and share the same port on the switch. This shared physical link has the following implications for the VLAN configuration on the network:

- The current VLANs might be configured on an IP subnet basis. However, an additional IP address might not be available to assign the phone to the same subnet as other devices connect to the same port.

- Data traffic present on the data/native VLAN may reduce the quality of VoIP traffic.

- Network security may indicate a need to isolate the VLAN voice traffic from the VLAN data traffic.

Resolve these issues by isolating the voice traffic onto a separate VLAN. The switch port to which the phone connects would be configured to have separate VLANs for carrying:

- Voice traffic to and from the IP phone (auxiliary VLAN, on the Cisco Catalyst 6000 series, for example)

- Data traffic to and from the PC that connects to the switch through the access port of the IP phone (native VLAN)

Isolation of the phones on a separate, auxiliary VLAN improves the quality of the voice traffic and allows a large number of phones to be added to an existing network where not enough IP addresses exist for each phone.

Phone Configuration Files

Phone configuration files are stored on the TFTP server and define Cisco Unified Communications Manager connection parameters. In general, whenever you make a change in Cisco Unified Communications Manager that requires the phone to reset, a change is made automatically to the phone configuration file.

Configuration files also contain information about the image load that the phone should be running. If this image load differs from the one currently that is loaded on a phone currently, the phone contacts the TFTP server to request the required load files. These load files are digitally signed to ensure the authenticity of the file source.

In addition, if the device security mode in the configuration file is set to Authenticated and the CTL file on the phone has a valid certificate for Cisco Unified Communications Manager, the phone establishes a TLS connection to Cisco Unified Communications Manager. Otherwise, the phone establishes a TCP connection. For SIP phones, a TLS connection requires that the transport protocol in the phone configuration file be set to TLS, which corresponds to the transport type in the SIP Security Profile in Cisco Unified Communications Manager Administration.

Note

If the device security mode in the configuration file is set to Authenticated or Encrypted but the phone has not received a CTL or ITL file, the phone tries four times to obtain the file so it can register securely.

Note

Cisco Extension Mobility Cross Cluster is an exception, in that the phone permits a TLS connection to Cisco Unified Communications Manager for secure signaling even without the CTL file.

If you configure security-related settings in Cisco Unified Communications Manager Administration, the phone configuration file contains sensitive information. To ensure the privacy of a configuration file, you must configure it for encryption. For more information, see the Cisco Unified Communications Manager Security Guide, "Configuring Encrypted Phone Configuration Files" chapter.

A phone requests a configuration file whenever it resets and registers with Cisco Unified Communications Manager.

A phone accesses a default configuration file named XmlDefault.cnf.xml only when the phone has not received a valid Trust List file that contains a certificate assigned to Cisco Unified Communications Manager and TFTP.

If autoregistration is not enabled and you did not add the phone to the Cisco Unified Communications Manager database, the phone system rejects the phone registration request with Cisco Unified Communications Manager. The phone displays the Configuring IP message continuously until you either enable autoregistration or add the phone to the Cisco Unified Communications Manager database.

If the phone has registered previously, the phone accesses the configuration file named SEPmac_address.cnf.xml, where mac_address is the MAC address of the phone.

For SIP phones, the TFTP server generates these SIP configuration files:

- SIP IP Phone

- For unsigned and unencrypted files: SEP<mac>.cnf.xml

- For signed files: SEP<mac>.cnf.xml.sgn

- For signed and encrypted files: SEP<mac>.cnf.xml.enc.sgn

- Dial Plan: <dialplan>.xml

- Softkey Template: <softkey_template>.xml

The filenames derive from the MAC Address and Description fields in the Phone Configuration window of Cisco Unified Communications Manager. The MAC address uniquely identifies the phone. For more information, see the Cisco Unified Communications Manager Administration Guide.

For more information about the phone interaction with the TFTP server, see the Cisco Unified Communications Manager System Guide, "Cisco TFTP" chapter.

Phone Startup Process

When the Cisco Unified IP Phone connects to the VoIP network, the phone goes through a standard startup process that the following steps describe. Depending on your specific network configuration, not all of these process steps may occur on your Cisco Unified IP Phone.

Procedure

Step 1

Obtain power from the switch.

If a phone is not using external power, the switch provides in-line power through the Ethernet cable that is attached to the phone.

See Cisco Unified IP Phone Power and Startup Problems.

Step 2

Load the StoredPhone Image.

The Cisco Unified IP Phone has nonvolatile flash memory in which it stores firmware images and user-defined preferences. At startup, the phone runs a bootstrap loader that loads a phone image stored in flash memory. The phone uses this image to initialize its software and hardware.

See Startup Problems.

Step 3

Configure VLAN.

If the Cisco Unified IP Phone is connected to a Cisco switch, the switch next informs the phone of the voice VLAN defined on the switch port. The phone needs to know its VLAN membership before it can proceed with the Dynamic Host Configuration Protocol (DHCP) request for an IP address.

See Network Configuration Menu and Startup Problems.

Step 4

Obtain an IP Address.

If the Cisco Unified IP Phone uses DHCP to obtain an IP address, the phone queries the DHCP server to obtain one. If you do not use DHCP in your network, you must assign static IP addresses to each phone locally.

See Network Configuration Menu and Startup Problems.

Step 5

Access a TFTP Server.

In addition to assigning an IP address, the DHCP server directs the Cisco Unified IP Phone to a TFTP server. If the phone has a statically defined IP address, you must configure the TFTP server locally on the phone. The phone then contacts the TFTP server directly.

Note

You can also assign an alternative TFTP server to use instead of the one that DHCP assigns.

See Network Configuration Menu and Startup Problems.

Step 6

Request the CTL file.

The TFTP server stores the CTL file. This file contains the certificates that are necessary to establish a secure connection between the phone and Cisco Unified Communications Manager.

See the Cisco Unified Communications Manager Security Guide, “Configuring the Cisco CTL Client” chapter.

Step 7

Request the ITL file.

The phone requests the ITL file after it requests the CTL file. The ITL file contains the certificates of the entities that the phone can trust. The certificates are used to authenticate a secure connection with the servers or to authenticate a digital signature that the servers sign.

See the Cisco Unified Communications Manager Security Guide, “Security by Default” chapter.

Step 8

Request the Configuration File.

The TFTP server has configuration files, which define parameters for connecting to Cisco Unified Communications Manager and other information for the phone.

See Phone Configuration Files and Startup Problems.

Step 9

Contact Cisco Unified Communications Manager.

The configuration file defines how the Cisco Unified IP Phone communicates with Cisco Unified Communications Manager and provides a phone with the load ID. After the phone obtains the file from the TFTP server, the phone attempts to make a connection to the highest priority Cisco Unified Communications Manager on the list. If the security profile of the phone is configured for secure signaling (encrypted or authenticated), and Cisco Unified Communications Manager is set to secure mode, the phone makes a TLS connection. Otherwise, it makes a nonsecure TCP connection.

If the phone was manually added to the database, Cisco Unified Communications Manager identifies the phone. If the phone was not manually added to the database and autoregistration is enabled in Cisco Unified Communications Manager, the phone attempts to autoregister in the Cisco Unified Communications Manager database.

Note

Autoregistration is disabled when you configure the CTL client. In this case, the phone must be manually added to the Cisco Unified Communications Manager database.

See Phone Configuration Files and Startup Problems.

Cisco Unified Communications Manager Phone Addition Methods

Before you install the Cisco Unified IP Phone, you must choose a method for adding phones to the Cisco Unified Communications Manager database.

The following table provides an overview of the methods for adding phones to the Cisco Unified Communications Manager database.

Cisco Unified Communications Manager Phone Addition Methods

Method

Requires MAC address?

Notes

Autoregistration

No

Results in automatic assignment of directory numbers.

Not available when security or encryption is enabled.

Autoregistration with TAPS

No

Requires autoregistration and the Bulk Administration Tool (BAT); updates the Cisco Unified Communications Manager database with the MAC address and DNs for the device when user calls TAPS from the phone.

Use Cisco Unified Communications Manager Administration

Yes

Requires phones to be added individually.

Use BAT

Yes

Can add groups of same model of phone.

Can schedule when phones are added to the Cisco Unified Communications Manager database.

- Autoregistration Phone Addition

- Autoregistration and TAPS Phone Addition

- Cisco Unified Communications Manager Administration Phone Addition

- Add Phones with BAT

Autoregistration Phone Addition

If you enable autoregistration before you begin installing phones, you can:

- Add phones without first gathering MAC addresses from the phones.

- Automatically add a Cisco Unified IP Phone to the Cisco Unified CM database when you physically connect the phone to your IP telephony network. During autoregistration, Cisco Unified Communications Manager assigns the next available sequential directory number to the phone.

- Quickly enter phones into the Cisco Unified Communications Manager database and modify any settings, such as the directory numbers, from Cisco Unified Communications Manager.

- Move autoregistered phones to new locations and assign them to different device pools without affecting their directory numbers.

Note

Cisco recommends that you use autoregistration to add fewer than 100 phones to your network. To add more than 100 phones to your network, use the Bulk Administration Tool (BAT).

Autoregistration is disabled by default. In some cases, you might not want to use autoregistration; for example, if you want to assign a specific directory number to the phone. For information about enabling autoregistration, see "Enable autoregistration" section in the Cisco Unified Communications Manager Administration Guide.

Note

When you configure the cluster for mixed mode through the Cisco CTL client, autoregistration is automatically disabled. When you configure the cluster for nonsecure mode through the Cisco CTL client, autoregistration is automatically enabled.

Autoregistration and TAPS Phone Addition

You can add phones with autoregistration and TAPS, the Tool for Auto-Registered Phones Support, without first gathering MAC addresses from phones.

TAPS works with the Bulk Administration Tool (BAT) to update a batch of phones that were already added to the Cisco Unified Communications Manager database with dummy MAC addresses. Use TAPS to update MAC addresses and download predefined configurations for phones.

Note

Cisco recommends that you use autoregistration and TAPS to add less than 100 phones to your network. To add more than 100 phones to your network, use the Bulk Administration Tool (BAT).

To implement TAPS, dial a TAPS directory number and follow the voice prompts. When the process completes, the phone has downloaded the directory number and other settings, and the phone is updated in Cisco Unified Communications Manager Administration with the correct MAC address.

Autoregistration must be enabled in Cisco Unified Communications Manager Administration (System > Cisco Unified CM) for TAPS to function.

Note

When you configure the cluster for mixed mode through the Cisco CTL client, autoregistration is automatically disabled. When you configure the cluster for nonsecure mode through the Cisco CTL client, autoregistration is automatically enabled.

For more information, see "Bulk Administration" chapter in the Cisco Unified Communications Manager Administration Guide and the "Tool for Auto-Registered Phones Support" chapter in the Cisco Unified Communications Manager Bulk Administration Guide.

Cisco Unified Communications Manager Administration Phone Addition

You can add phones individually to the Cisco Unified Communications Manager database by using Cisco Unified Communications Manager Administration. To do so, you first need to obtain the MAC address for each phone.

After you have collected MAC addresses, in Cisco Unified Communications Manager Administration, choose Device > Phone and click Add New to begin.

For complete instructions and conceptual information about Cisco Unified Communications Manager, see the Cisco Unified Communications Manager Administration Guide and the Cisco Unified Communications Manager System Guide.

Before you install a Cisco Unified IP Phone, you must decide how to configure the phone in your network. Then you can install the phone and verify the functionality. For more information, see Cisco Unified IP Phones and Telephony Networks.

Before You Begin

Before you install the Cisco Unified IP Phone, review the requirements in these sections:

- Network Requirements

- Cisco Unified Communications Manager Setup

Network Requirements

For the Cisco Unified IP Phone to successfully operate as a Cisco Unified IP Phone endpoint in your network, your network must meet these requirements:

- Working VoIP network:

- VoIP configured on your Cisco routers and gateways

- Cisco Unified Communications Manager 4.x and later installed in your network and configured to handle call processing

- IP network that supports DHCP or manual assignment of IP address, gateway, and subnet mask

Note

The Cisco Unified IP Phone displays the date and time from Cisco Unified Communications Manager. The time displayed on the phone can differ from the Cisco Unified Communications Manager time by up to 10 seconds. The Cisco Unified Communications Manager server does not display the local time if it is located in a different time zone than the phones.

Cisco Unified Communications Manager Setup

The Cisco Unified IP Phone requires Cisco Unified Communications Manager to handle call processing. See the Cisco Unified Communications Manager Administration Guide or the context-sensitive help in the Cisco Unified Communications Manager application to ensure that Cisco Unified Communications Manager is set up properly to manage the phone and to properly route and process calls.

If you plan to use autoregistration, verify that it is enabled and properly configured in Cisco Unified Communications Manager before you connect any Cisco Unified IP Phone to the network. For information about enabling and configuring autoregistration, see the Cisco Unified Communications Manager Administration Guide.

You must use Cisco Unified Communications Manager to configure and assign telephony features to the Cisco Unified IP Phones.

In Cisco Unified Communications Manager, you can add users to the database and associate them with specific phones. In this way, users gain access to web pages that allow them to configure items such as call forward, speed dial, and voice message system options.

Headset

Although Cisco performs internal tests of third-party headsets for use with the Cisco Unified IP Phones, Cisco does not certify or support products from headset or handset vendors.

We recommend the use of good quality external devices, for example, headsets that are screened against unwanted radio frequency (RF) and audio frequency (AF) signals. Depending on the quality of headsets and their proximity to other devices, such as mobile phones and two-way radios, some audio noise or echo may still occur. An audible hum or buzz may be heard by either the remote party of by both the remote party and the Cisco Unified IP Phone user. A range of outside sources can cause humming or buzzing sounds; for example, electric lights, electric motors, or large PC monitors. For more information, see External Device Use.

Note

In some cases, use of a local power cube or power injector may reduce or eliminate hum.

These environmental and hardware inconsistencies in the locations where Cisco Unified IP Phones are deployed mean that no single headset solution is optimal for all environments.

We recommend that customers test headsets in their intended environment to determine performance prior to purchase and large-scale deployment.

Note

The Cisco Unified IP Phone 7975G, 7971G-GE, 7970G, 7965G, and 7945G supports wideband headsets.

- Audio Quality

- Headset Connection

- Disable Headset

- Wireless Headset

- External Device Use

Audio Quality

Beyond physical, mechanical, and technical performance, the audio portion of a headset must sound good to the user and the party on the far end. Sound quality is subjective and Cisco cannot guarantee the performance of any headsets or handsets. However, a variety headsets from leading headset manufacturers have been reported to perform well with Cisco Unified IP Phones.

For additional information, see the Headsets for Cisco Unified IP Phones and Desktop Clients page on Cisco.com.

Note

The Cisco Unified IP Phone 7971G-GE and 7970G do not support wireless headsets.

Headset Connection

To connect a headset to the Cisco Unified IP Phone, plug it into the Headset port on the back of the phone. Press the Headset button on the phone to place and answer calls by using the headset.

You can use the headset with all Cisco Unified IP Phone features, including the Volume and Mute buttons. Use these buttons to adjust the ear piece volume and to mute the speech path from the headset microphone.

Procedure

Step 1

Choose Device > Phone and locate the phone you want to modify.

Step 2

In the Phone Configuration window, select Enable for Headset Hookswitch Control.

External Device Use

Cisco recommends the use of good quality external devices, such as speakers, microphones, and headsets that are shielded (screened) against unwanted radio frequency (RF) and audio frequency (AF) signals.

Depending on the quality of these devices and their proximity to other devices, such as mobile phones or two-way radios, some audio noise may still occur. In these cases, Cisco recommends that you take one or more of the following actions:

- Move the external device away from the source of the RF or AF signals.

- Route the external device cables away from the source of the RF or AF signals.

- Use shielded cables for the external device, or use cables with a better shield and connector.

- Shorten the length of the external device cable.

- Apply ferrites or other such devices on the cables for the external device.

Cisco cannot guarantee the performance of the system because Cisco has no control over the quality of external devices, cables, and connectors. The system performs adequately when suitable devices are attached with good quality cables and connectors.

Caution

In European Union countries, use only external headsets that are fully compliant with the EMC Directive [89/336/EC].

Install Cisco Unified IP Phone

You must connect the Cisco Unified IP Phone to the network and to a power source before use. For the description of how to connect the cables to the phone, see Cisco Unified IP Phone Cable Installation.

You can mount the Cisco Unified IP Phone on the wall by using the footstand as a mounting bracket, or you can use special brackets available in a Cisco Unified IP Phone wall mount kit. Wall mount kits must be ordered separately from the phone.

If you attach the Cisco Unified IP Phone to a wall with the standard footstand and not the wall mount kit, you need to supply the following tools and parts:

- Screwdriver

- Screws to secure the Cisco Unified IP Phone to the wall

See the following figure for a graphical overview of the phone parts.

Parts Used to Wall Mount the Cisco Unified IP Phone

1

Footstand adjustment button: Raises and lowers adjustment plate

2

Wall mounting screw holes

3

Adjustment plate: Raises and lowers phone vertically

Before you begin

To ensure that the handset attaches securely to a wall-mounted phone, remove the handset wall hook from the handset rest, rotate the hook 180 degrees, and reinsert the hook. Turning the hook exposes a lip on which the handset catches when the phone is vertical. For an illustrated procedure, see Installing the Wall Mount Kit for the Cisco Unified IP Phone at:

http://www.cisco.com/en/US/products/hw/phones/ps379/prod_installation_guides_list.html

Caution

Use care not to damage wires or pipes located inside the wall when securing screws to wall studs.

Procedure

Step 1

Push in the footstand adjustment button.

Step 2

Adjust the footstand, so it is flat against the back of the phone.

Step 3

Insert two screws into a wall stud, matching them to the two screw holes on the back of the footstand.

The keyholes fit standard phone jack mounts.

Step 4

Hang the phone on the wall.

Phone Startup Process

After the Cisco Unified IP Phone has power connected to it, the phone begins its startup process by cycling through these steps.

1. These buttons flash on and off in sequence:

- Headset (Only if the handset is off-hook when the phone powers up. In this case, hang up the handset within 3 seconds or the phone launches its secondary load instead of its primary load.)

- Mute

- Speaker

2. Some or all of the line keys flash orange.

Caution

If the line keys flash red in sequence after flashing yellow, do not power down the phone until the sequence of red flashes completes. This sequence can take several minutes to complete.

3. Some or all of the line keys flash green.

Normally, this sequence takes just a few seconds. However, if the phone flash memory is erased or the phone load is corrupted, the sequence of green flashes will continue while the phone begins a software update procedure. If the phone performs this procedure, the following buttons light to indicate progress:

- Headset: Phone is waiting for the network and completing CDP and DHCP configuration. A DHCP server must be available in your network.

- Mute: Phone is downloading images from the TFTP server.

- Speaker: Phone is writing images to its flash memory.

4. The phone screen displays the Cisco Systems, Inc., logo screen.

5. These messages display as the phone starts:

- Verifying load (if the phone load does not match the load on the TFTP server). If this message displays, the phone start up again and repeats step 1 through step 4 above.

- Configuring IP

- Updating the Trust List

- Updating Locale

- Configuring Unified CM List

- Registering

6. The main phone screen displays:

- Current date and time

- Primary directory number

- Additional directory numbers and speed dial numbers, if configured

- Softkeys

If the phone successfully passes through these stages, it has started up properly. If the phone does not start up properly, see Startup Problems.

Network Settings

If you are not using DHCP in your network, you must configure these network settings on the Cisco Unified IP Phone after you install the phone on the network:

- IP address

- IP subnet information (subnet mask for IPv4 and subnet prefix length for IPv6)

- Default gateway IP address

- TFTP server IP address

You may also configure these optional settings as necessary:

- Domain name

- DNS server IP address

You can initiate the installation of a Locally Significant Certificate (LSC) from the Security Configuration menu on the phone. This menu also lets you update or remove an LSC.

If you use a Third Party CA to sign LSCs, note that the Cisco Unified IP Phone 7900 Series only support SHA-1 as the algorithm to sign certificates. The phones do not support SHA-2 (SHA256). For more information on the use of a Third Party CA to sign LSCs, see CUCM Third-Party CA-Signed LSCs Generation and Import Configuration Example in https://www.cisco.com/c/en/us/support/docs/unified-communications/unified-communications-manager-callmanager/118779-configure-cucm-00.html.

Depending on how you have configured the CAPF, this procedure installs an LSC, updates an existing LSC, or removes an existing LSC.

Before you begin

Make sure that the appropriate Cisco Unified Communications Manager and the Certificate Authority Proxy Function (CAPF) security configurations are complete:

- The CTL file or ITL file should have a CAPF certificate.

- On Cisco Unified Communications Operating System Administration, verify that the CAPF certificate has been installed.

- The CAPF is running and configured.

For more information, see Cisco Unified Communications Manager Security Guide.

Procedure

Step 1

Obtain the CAPF authentication code that was set when the CAPF was configured.

Step 2

For more information, see the Cisco Unified Communications Manager Features and Services Guide, "Call Pickup" chapter.

Automatic Port Synchronization

When the Cisco Unified Communications Manager administrator uses the Remote Port Configuration feature to set the speed and duplex function of an IP phone remotely, loss of packets can occur if one port is slower than the other.

The Automatic Port Synchronization feature synchronizes the ports to the lowest speed among the two ports, which eliminates packet loss. When automatic port synchronization is enabled, it is recommended that both ports be configured for autonegotiate. If one port is enabled for autonegotiate and the other is at a fixed speed, the phone synchronizes to the fixed port speed.

Note

If both the ports are configured for fixed speed, the Automatic Port Synchronization feature is ineffective.

Note

The Remote Port Configuration and Automatic Port Synchronization features are compatible only with IEEE 802.3AF Power of Ethernet (PoE) switches. Switches that support only Cisco Inline Power are not compatible. Enabling this feature on phones that are connected to these types of switches could result in loss of connectivity to Cisco Unified Communications Manager, if the phone is powered by PoE.

To configure the parameter in the Cisco Unified Communications Manager Administration application, choose Device > Phone, select the appropriate IP phones, and scroll to the Product Specific Configuration Layout pane.

To configure the setting on multiple phones simultaneously, enable Automatic Port Synchronization in the Enterprise Phone Configuration (System > Enterprise Phone Configuration).

Barge (and cBarge)

Allows a user to join a nonprivate call on a shared phone line. Barge features include cBarge and Barge.

- cBarge adds a user to a call and converts it into a conference, allowing the user and other parties to access conference features.

- Barge adds a user to a call but does not convert the call into a conference.

The phones support Barge in two conference modes:

- Built-in conference bridge at the target device (the phone that is being barged). This mode uses the Barge softkey.

- Shared conference bridge. This mode uses the cBarge softkey.

No configuration required.

Secure and Nonsecure Indication Tone

When a phone is configured as secure (encrypted and trusted) in Cisco Unified Communications Manager, it can be given a protected status. Afterward, the protected phone can be configured to play an indication tone at the beginning of a call:

- Protected Device: To change the status of a secure phone to protected, check the "Protected Device" check box in Cisco Unified Communications Manager Administration (Device > Phone > Phone Configuration).

- Play Secure Indication Tone: To enable the protected phone to play a secure or nonsecure indication tone, set the "Play Secure Indication Tone" to True. (The default is False.) You set this option in Cisco Unified Communications Manager Administration (System > Service Parameters). Select the server and then the Cisco CallManager service. In the Service Parameter Configuration window, select the option in the Feature - Secure Tone area. (The default is False.)

Only protected phones hear these secure or nonsecure indication tones. (Nonprotected phones never hear tones.) If the overall call status changes during the call, the indication tone changes  accordingly. At that time, the protected phone plays the appropriate tone.

A protected phone plays a tone or not under these circumstances:

- When the option to play the tone is enabled Play Secure Indication Tone option is enabled (True):

- When end-to-end secure media is established and the call status is secure, the phone plays the secure indication tone (three long beeps with pauses).

- When end-to-end nonsecure media is established and the call status is nonsecure, the phone plays the nonsecure indication tone (six short beeps with brief pauses).

- If the Play Secure Indication Tone option is disabled, no tone plays.

No configuration required.

Secure Extension Mobility Cross Cluster

Secure Extension Mobility Cross Cluster (EMCC) feature enables a user configured in one cluster to log into a Cisco Unified IP Phone in another cluster. The users from a home cluster log into a Cisco Unified IP Phone at a visiting cluster. The visiting cluster fails to log into home cluster in secure mode.

For more information, see Cisco Unified Communications Manager Features and Services Guide, “Cisco Extension Mobility Cross Cluster” chapter.

Secure Conference

Allows secure phones to place conference calls by using a secured conference bridge.

As new participants are added by using Confrn, Join, cBarge, Barge softkeys or Meet-Me conferencing, the secure call icon displays as long as all participants use secure phones.

The Conference List displays the security level of each conference participant. Initiators can remove nonsecure participants from the Conference List. Noninitiators can add or remove conference participants if the Advance Adhoc Conference parameter is set.

To support this feature, you must configure corporate directories.

- Personal Directory: Allows a user to store a set of personal numbers.

To support this feature, you must provide the user with software to configure the personal directory.

- Corporate Directory Setup

- Personal Directory Setup

Corporate Directory Setup

Cisco Unified Communications Manager uses a Lightweight Directory Access Protocol (LDAP) directory to store authentication and authorization information about users of Cisco Unified Communications Manager applications that interface with Cisco Unified Communications Manager. Authentication establishes a user right to access the system. Authorization identifies the telephony resources that a user is permitted to use, such as a specific telephone extension.

For more information on directories, see the Cisco Unified Communications Manager System Guide, "Understanding Directory" chapter.

To install and set up these features, see the Cisco Unified Communications Manager Administration Guide, "LDAP System Configuration", "LDAP Directory Configuration", and "LDAP Authentication Configuration" chapters.

After completing the LDAP directory configuration, users can use the Corporate Directory service on their Cisco Unified IP Phone to look up users in the corporate directory.

Personal Directory Setup

Personal Directory consists of the following features:

- Personal Address Book (PAB)

- Personal Fast Dials (Fast Dials)

- Address Book Synchronization Tool (TABSync)

Users can access Personal Directory features by these methods:

- From a web browser: Users can access the PAB and Fast Dials features from the Cisco Unified Communications Manager User Options web pages.

- From the Cisco Unified IP Phone: Users can choose Directories > Personal Directory to access the PAB and Fast Dials features from their phones.

- From a Microsoft Windows application: Users can use the TABSync tool to synchronize their PABs with Microsoft Windows Address Book (WAB). Customers who want to use the Microsoft Outlook Address Book (OAB) should begin by importing the data from the OAB into the Windows Address Book (WAB). TabSync can then be used to synchronize the WAB with Personal Directory.

To ensure that Cisco Unified IP Phone Address Book Synchronizer users have access only to end user data that pertains to them, activate the Cisco UXL Web Service in Cisco Unified Serviceability.

To configure Personal Directory from a web browser, users must access their User Options web pages. You must provide users with a URL and login information.

To synchronize with Microsoft Outlook, users must install the TABSync utility, which you provide. For more information, see Obtain Cisco Unified IP Phone Address Book Synchronizer and Cisco Unified IP Phone Address Book Synchronizer Deployment.

EnergyWise Setup on Cisco Unified IP Phone

To reduce power consumption, you can configure the phone to sleep (power down) and wake (power up) if your system includes an EnergyWise controller (for example, a Cisco Switch with the EnergyWise feature enabled).

You configure settings in Cisco Unified Communications Manager Administration to enable EnergyWise and configure sleep and wake times. These parameters are closely tied to the phone display configuration parameters.

When EnergyWise is enabled and a sleep time is set, the phone sends a request to the switch to wake it up at the configured time. The switch sends back either an acceptance or a rejection of the request. If the switch rejects the request or if the switch does not reply, the phone does not power down. If the switch accepts the request, the idle phone goes to sleep, reducing its power consumption to a predetermined level. A phone that is not idle sets an idle timer, and goes to sleep after the timer expires.

At the scheduled wake time, the system restores power to the phone, waking it up. To wake up the phone before the wake time, you must power on the phone from the switch. For more information, see the switch documentation.

The following table explains the Cisco Unified Communications Manager Administration fields that control the EnergyWise settings. You configure these fields in Cisco Unified Communications Manager Administration by choosing Device > Phone. You can also configure EnergyWise parameters in the Enterprise Phone Configuration and Common Phone Profile Configuration windows.

EnergyWise Configuration Fields

Field

Description

Enable Power Save Plus

Selects the schedule of days for which the phone powers off. Select multiple days by pressing and holding the Control key while clicking on the days for the schedule.

By default, no days are selected.

When Enable Power Save is checked, you receive a message to warn about emergency (e911) concerns.

Caution

While Power Save Plus mode (hereafter, the mode) is in effect, endpoints configured for the mode are disabled for emergency calling and from receiving inbound calls. By selecting this mode, you agree to the following: (i) you are taking full responsibility for providing alternate methods for emergency calling and receiving calls while the mode is in effect; (ii) Cisco has no liability in connection with your selection of the mode and all liability in connection with enabling the mode is your responsibility; and (iii) you will inform users of the effects of the mode on calls, calling and otherwise.

Note

To disable Power Save Plus, you must uncheck the Allow EnergyWise Overrides check box. Leaving the Allow EnergyWise Overrides checked with no days selected in the Enable Power Save Plus field does not disable Power Save Plus.

Phone On Time

Determines when the phone automatically turns on for the days selected in the Enable Power Save Plus field.

Enter the time in this field in 24 hour format, where 00:00 is midnight.

For example, to automatically power up the phone at 7:00 a.m. (0700), enter 7:00. To power up the phone at 2:00 p.m. (1400), enter 14:00.

The default value is blank, which means 00:00.

Phone Off Time

The time of day that the phone powers down for the days selected in the Enable Power Save Plus field. If the Phone On Time and the Phone Off Time fields contain the same value, the phone does not power down.

Enter the time in this field in 24 hour format, where 00:00 is midnight.

For example, to automatically power down the phone at 7:00 a.m. (0700), enter 7:00. To power down the phone at 2:00 p.m. (1400), enter 14:00.

The default value is blank, which means 00:00.

Phone Off Idle Timeout

The length of time that the phone must be idle before the phone powers down.

The range of the field is 20 to 1440 minutes.

The default value is 60 minutes.

Enable Audible Alert

When enabled, instructs the phone to play an audible alert starting at 10 minutes before to the time specified in the Phone Off Time field.

The audible alert uses the phone ringtone, which briefly plays at specific times during the 10-minute alerting period. The alerting ringtone plays at the user-designated volume level. The audible alert schedule is:

- 10 minutes before power down, play the ringtone four times.

- 7 minutes before power down, play the ringtone four times.

- 4 minutes before power down, play the ringtone four times.

- 30 seconds before power down, play the ringtone 15 times or until the phone powers down.

This check box applies only if the Enable Power Save Plus list box has one or more days selected.

EnergyWise Domain

The EnergyWise domain that the phone is in. The maximum length is 127 characters.

EnergyWise Secret

The security secret password that is used to communicate with the endpoints in the EnergyWise domain.

The maximum length is 127 characters.

Allow EnergyWise Overrides

This check box determines if you will allow the EnergyWise domain controller policy to send power level updates to the phones. The following conditions apply:

1. If the phone is in full power save mode and the level is set to any standby level, the phone will go to Power Save when idle and remain in that mode until the next Cisco Unified CM scheduled power level change or user interaction.

2. If the phone is in Power Save or at full power and the level is set to any nonoperational level, the phone will power down when idle and remain powered off until the switch reapplies power or the user wakes the phone.

For example, assume the Phone Off Time is set to 22:00 (10:00 p.m.), the value in the Phone On Time field is 06:00 (6:00 a.m.), and the Enable Power Save Plus has one or more days selected.

- If EnergyWise directs the phone to turn off at 20:00 (8:00 p.m.), then the directive remains in effect until the configured Phone On Time at 6:00 a.m., assuming no phone user intervention occurs.

- At 6 a.m., the phone will turn on and resume receiving its power level changes from the settings in Cisco Unified Communications Manager Administration.

- To change the power level on the phone again, EnergyWise must reissue a new power level change command.

Note

To disable Power Save Plus, you must uncheck the Allow EnergyWise Overrides check box. Leaving the Allow EnergyWise Overrides checked with no days selected in the Enable Power Save Plus field does not disable Power Save Plus.

- Custom Phone Ring Creation

- Custom Background Images

- Wideband Codec Setup

- Idle Display Setup

- Cisco Unified IP Phone Backlight

Configuration File Customization and Modification

You can modify configuration files and add customized files to the TFTP directory. You can modify files or add customized files to the TFTP directory in Cisco Unified Communications Operating System Administration, from the TFTP Server File Upload window. For information about how to upload files to the TFTP folder on a Cisco Unified Communications Manager server, see the Cisco Unified Communications Manager System Guide.

You can obtain a copy of the Ringlist.xml or Ringlist-wb.xml files and the List.xml file from the system using the following admin command-line interface (CLI) "file" commands:

- admin:file

- file list

- file view

- file search

- file get

- file dump

- file tail

- file delete

For more information, see the Cisco Intercompany Media Engine Command Line Interface Reference Guide.

Custom Phone Ring Creation

The Cisco Unified IP Phone ships with two default ring types that are implemented in hardware: Chirp1 and Chirp2. Cisco Unified Communications Manager also provides a default set of additional phone ring sounds that are implemented in software as pulse code modulation (PCM) files. The PCM files, along with an XML file (named Ringlist.xml) that describes the ring list options that are available at your site, exist in the TFTP server on each Cisco Unified Communications Manager server.

For more information, see the "Custom Phone Rings" chapter in the Cisco Unified Communications Manager Features and Services Guide and the "Software Upgrades" chapter in the Cisco Unified Communications Operating System Administration Guide.

The following sections describe how you can customize the phone rings that are available at your site by creating PCM files and editing the Ringlist.xml file:

- Ringlist.xml File Format Requirements

- PCM File Requirements for Custom Ring Types

- Set Up Custom Phone Ring

Ringlist.xml File Format Requirements

The Ringlist.xml file defines an XML object that contains a list of phone ring types. This file includes up to 50 ring types. Each ring type contains a pointer to the PCM file that is used for that ring type and the text that appears on the Ring Type menu on a Cisco Unified IP Phone for that ring. The Cisco TFTP server for each Cisco Unified Communications Manager contains this file.

The CiscoIPPhoneRinglist XML object uses the following simple tag set to describe the information:

<CiscoIPPhoneRingList>
<Ring>
<DisplayName/>
<FileName/>
</Ring>
</CiscoIPPhoneRingList>

The following characteristics apply to the definition names. You must include the required DisplayName and FileName for each phone ring type.

- DisplayName specifies the name of the custom ring for the associated PCM file that displays on the Ring Type menu of the Cisco Unified IP Phone.

- FileName specifies the name of the PCM file for the custom ring to associate with DisplayName.

Note

The DisplayName and FileName fields must not exceed 25 characters in length.

This example shows a Ringlist.xml file that defines two phone ring types:

<CiscoIPPhoneRingList>
<Ring>
<DisplayName>Analog Synth 1</DisplayName>
<FileName>Analog1.raw</FileName>
</Ring>
<Ring>
<DisplayName>Analog Synth 2</DisplayName>
<FileName>Analog2.raw</FileName>
</Ring>
</CiscoIPPhoneRingList>

PCM File Requirements for Custom Ring Types

The PCM files for the rings must meet the following requirements for proper playback on Cisco Unified IP Phones:

- Raw PCM (no header)

- 8000 samples per second

- 8 bits per sample

- Mu-law compression

- Maximum ring size = 16080 samples

- Minimum ring size = 240 samples

- Number of samples in the ring = multiple of 240.

- Ring start and end at zero crossing.

To create PCM files for custom phone rings, use any standard audio editing package that supports these file format requirements.

Set Up Custom Phone Ring

To create custom phone rings for the Cisco Unified IP Phone, perform these steps:

Procedure

Step 1

Create a PCM file for each custom ring (one ring per file). Ensure the PCM files comply with the format guidelines that are listed in PCM File Requirements for Custom Ring Types.

Step 2

Upload the new PCM files that you created to the Cisco TFTP server for each Cisco Unified Communications Manager in your cluster. For more information, see the "Software Upgrades" chapter in Cisco Unified Communications Operating System Administration Guide.

Step 3

Use a text editor to edit the Ringlist.xml file. See Ringlist.xml File Format Requirements for information about how to format this file and for a sample Ringlist.xml file.

Step 4

Save your modifications and close the Ringlist.xml file.

Step 5

To cache the new Ringlist.xml file, stop and start the TFTP service by using Cisco Unified Serviceability or disable and reenable the "Enable Caching of Constant and Bin Files at Startup" TFTP service parameter (that is found in the Advanced Service Parameters area.)

Custom Background Images

You can provide users with a choice of background images for the LCD screen on their phones. Users can select a background image by choosing Settings > User Preferences > Background Images on the phone.

The image choices that users see come from PNG images and an XML file (called List.xml) that are stored on the TFTP server that the phone uses. By storing your own PNG files and editing the XML file on the TFTP server, you can designate the background images from which users can choose. In this way, you can provide custom images, such as your company logo.

The following sections describe how you can customize the background images that are available at your site by creating your own PNG files and editing the List.xml file.

- List.xml File Format Requirements

- PNG File Requirements for Custom Background Images

- Set Up Custom Background Image

List.xml File Format Requirements

The List.xml file defines an XML object that contains a list of background images. The List.xml file is stored in the following subdirectory on the TFTP server:

- /Desktops/320x212x16 for Cisco Unified IP Phone 7945 and 7965

- /Desktops/320x212x12 for Cisco Unified IP Phone 7971 and 7970

- /Desktops/320x212x12 for Cisco Unified IP Phone 7975

Tip

If you are manually creating the directory structure and the List.xml file, you must ensure that the directories and files can be accessed by the user\CCMService, which is used by the TFTP service.

For more information, see "Software Upgrades" chapter in Cisco Unified Communications Operating System Administration Guide.

The List.xml file can include up to 50 background images. The images are in the order that they appear in the Background Images menu on the phone. For each image, the List.xml file contains one element type, called ImageItem. The ImageItem element includes these two attributes:

- Image: Uniform resource identifier (URI) that specifies where the phone obtains the thumbnail image that will appear on the Background Images menu on a Phone.

- URL: URI that specifies where the phone obtains the full size image.

The following example (for a Cisco Unified IP Phone 7971G-GE and 7970G) shows a List.xml file that defines two images. The required Image and URL attributes must be included for each image. The TFTP URI that displays in the example is the only supported method for linking to full size and thumbnail images. HTTP URL support is not provided.

List.xml Example

<CiscoIPPhoneImageList><ImageItem Image=”TFTP:Desktops/320x212x12/TN-Fountain.png” URL=”TFTP:Desktops/320x212x12/Fountain.png”/>
<ImageItem Image=”TFTP:Desktops/320x212x12/TN-FullMoon.png” URL=”TFTP:Desktops/320x212x12/FullMoon.png”/>
</CiscoIPPhoneImageList>

The Cisco Unified IP Phone firmware includes a default background image. This image is not defined in the List.xml file. The default image is always the first image that appears in the Background Images menu on the phone.

PNG File Requirements for Custom Background Images

Each background image requires two PNG files:

- Full size image: Version that displays on the on the phone.

- Thumbnail image: Version that displays on the Background Images screen from which users can select an image. The thumbnail image must be 25% of the size of the full-size image.

Tip

Many graphics programs provide a feature that will resize a graphic. An easy way to create a thumbnail image is to first create and save the full size image, then use the sizing feature in the graphics program to create a version of that image that is 25% of the original size. Save the thumbnail version with a different name than the full-size image.

The PNG files for background images must meet the following requirements for proper display on the Cisco Unified IP Phone:

- Full size image: 320 pixels (width) X 216 pixels (height)

- Thumbnail image: 80 pixels (width) X 53 pixels (height)

- Color palette:

- For Cisco Unified IP Phone 7971G-GE and 7970G)—Includes up to 12-bit color (4096 colors). You can use more than 12-bit color, but the phone will reduce the color palette to 12-bit before displaying the image. For best results, reduce the color palette of an image to 12-bit when you create a PNG file.

Tip: If you are using a graphics program that supports a posterize feature for specifying the number of tonal levels per color channel, set the number of tonal levels per channel to 16 (16 red X 16 green X 16 blue = 4096 colors).

- For Cisco Unified IP Phone 7975G, 7965G, and 7945G)—Includes up to 16-bit color (65535 colors). You can use more than 16-bit color, but the phone will reduce the color palette to 16-bit before displaying the image. For best results, reduce the color palette of an image to 16-bit when you create a PNG file.

Tip: If you are using a graphics program that supports a posterize feature for specifying the number of tonal levels per color channel, set the number of tonal levels per channel to 40 (40 red X 40 green X 40 blue = 64000 colors). This is as close as you can posterize to 65535 colors without exceeding the maximum.

Set Up Custom Background Image

To create custom background images for the Cisco Unified IP Phone, follow these steps:

Procedure

Step 1

Create two PNG files for each image (a full size version and a thumbnail version). Ensure the PNG files comply with the format guidelines that are listed in PNG File Requirements for Custom Background Images.

Step 2

Upload the new PNG files that you created to the following subdirectory in the TFTP server for Cisco Unified Communications Manager:

- /Desktops/320x216x16 for Cisco Unified IP Phone 7975G

- /Desktops/320x212x16 for Cisco Unified IP Phone 7965G and 7945G

Note

The file name and subdirectory parameters are case sensitive. Be sure to use the forward slash "/" when you specify the subdirectory path.

To upload the files, choose Software Upgrades > Upload TFTP Server File in Cisco Unified Communications Operating System Administration. For more information, see the "Software Upgrade" chapter in Cisco Unified Communications Operating System Administration Guide.

Note

If the folder does not exist, the folder is created and the files upload to the folder.

Step 3

You must also copy the customized images and files to the other TFTP servers that the phone may contact to obtain these files.

Note

Cisco recommends that you also store backup copies of custom image files in another location. You can use these backup copies if the customized files are overwritten when you upgrade Cisco Unified Communications Manager.

Step 4

Use a text editor to edit the List.xml file. See List.xml File Format Requirements for the location of this file, formatting requirements, and a sample file.

Step 5

Save your modifications and close the List.xml file.

Note

When you upgrade Cisco Unified Communications Manager, a default List.xml file will replace your customized List.xml file. After you customize the List.xml file, make a copy of the file and store it in another location. After upgrading Cisco Unified Communications Manager, replace the default List.xml file with your stored copy.

Step 6

To cache the new List.xml file, stop and start the TFTP service by using Cisco Unified Serviceability or disable and re-enable the Enable Caching of Constant and Bin Files at Startup TFTP service parameter (located in the Advanced Service Parameters).

Wideband Codec Setup

If Cisco Unified Communications Manager has been configured to use G.722 (G.722 is enabled by default for the Cisco Unified IP Phone) and if the far endpoint supports G.722, the call can connect using the G.722 codec in place of G.711. This situation occurs regardless of whether the user has enabled a wideband headset or wideband handset, but if either the headset or handset is enabled, the user may notice greater audio sensitivity during the call. Greater sensitivity means improved audio clarity but also means that more background noise can be heard by the far endpoint: noise such as rustling papers or nearby conversations. Even without a wideband headset or handset, some users may prefer the additional sensitivity of G.722. Other users may be distracted by the additional sensitivity of G.722.

Two parameters in Cisco Unified Communications Manager Administration affect whether wideband is supported for this Cisco Unified Communications Manager server or a specific phone:

- Advertise G.722 Codec: From Cisco Unified Communications Manager Administration, choose System > Enterprise Parameters. The default value of this enterprise parameter is True, which means that all Cisco Unified IP Phone models that are described in this administration guide and are registered to this Cisco Unified Communications Manager will advertise G.722 to Cisco Unified Communications Manager. For more information, see the Cisco Unified Communications Manager System Guide, "Cisco Unified IP Phones" chapter.

- Advertise G.722 Codec: From Cisco Unified Communications Manager Administration, choose Device > Phone. The default value of this product-specific parameter is to use the value specified in the enterprise parameter. If you want to override this on a per-phone basis, choose Enabled or Disabled in the advertises G.722 Codec parameter on the Product Specific Configuration area of the Phone Configuration window.

Idle Display Setup

You can specify an idle display that appears on the phone LCD screen. The idle display is an XML service that the phone invokes when the phone has been idle (not in use) for a designated period and no feature menu is open.

XML services that can be used as idle displays include company logos, product pictures, and stock quotes.

Configuration of the idle display requires these general steps:

1. Format an image for display on the phone.

2. Configure Cisco Unified Communications Manager to display the image on the phone.

For detailed instructions about creating and displaying the idle display, see Creating Idle URL Graphics on Cisco Unified IP Phone at this URL:

http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_tech_note09186a00801c0764.shtml

In addition, see the Cisco Unified Communications Manager Administration Guide or the Cisco Unified Communications Manager Bulk Administration Guide for the following information:

- Specify the URL of the idle display XML service:

- For a single phone: Idle field in the Cisco Unified Communications Manager Phone Configuration window

- For multiple phones simultaneously: URL Idle field on the Cisco Unified Communications Manager Enterprise Parameters configuration window, or the Idle field in the Bulk Administration Tool (BAT)

- Specify the length of time that the phone is not used before the idle display XML service is invoked:

- For a single phone: Idle Timer field on the Cisco Unified Communications Manager Phone configuration window

- For multiple phones simultaneously: URL Idle Time field on the Cisco Unified Communications Manager Enterprise Parameters configuration window, or the Idle Timer field in the Bulk Administration Tool (BAT)

From a phone, you can see settings for the idle display XML service URL and the length of time that the phone is not used before this service is invoked. To see these settings, choose Settings > Device Configuration and scroll to the Idle URL and the Idle URL Time parameters.

Cisco Unified IP Phone Backlight

To conserve power and ensure the longevity of the LCD screen on the phone, you can set the LCD to turn off when it is not needed.

You can configure settings in Cisco Unified Communications Manager Administration to turn off the display at a designated time on some days and all day on other days. For example, you may choose to turn off the display after business hours on weekdays and all day on Saturdays and Sundays.

When the display is off, the LCD screen is dark and disabled, and the Display button lights. You can take any of these actions to turn on the display any time it is off:

- Press any button on the phone.

If you press a button other than the Display button, the phone will take the action designated by that button in addition to turning on the display.

- Touch the touchscreen (or phone screen, whichever is applicable).

- Lift the handset.

When you turn the display on, it remains on until the phone remains idle for a designated length of time, then it turns off automatically.

Note

You can use the Display button to temporarily disable the touchscreen (or phone screen) for cleaning. See Cisco Unified IP Phone Cleaning for more information.

Note

The XSI Screen Width Enhancement feature, when implemented on Cisco Unified IP Phones, enhances the viewability of the Messages, Directories, and Services screens. These screens may appear in Normal mode or in Wide mode, depending on how the phone is set up. For information, see the Cisco Unified IP Phone Services Application Development Notes at http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_programming_reference_guides_list.html.

The following table explains the Cisco Unified Communications Manager Administration fields that control when the display turns on and off. You configure these fields in Cisco Unified Communications Manager Administration in the Product Specific configuration window. (You access this window by choosing Device > Phone from Cisco Unified Communications Manager Administration.)

You can view the display settings for a phone from the Power Save Configuration menu on the phone. For more information, see Power Save Configuration Menu.

Max Jitter

Maximum jitter observed since the receiving voice stream opened.

Rcvr Discarded

Number of RTP packets in the receiving voice stream that have been discarded (such as bad packets or packets received too late).

Note

The phone discards payload type 19 comfort noise packets that by Cisco Gateways generate, which increment this counter.

Rcvr Lost Packets

Missing RTP packets (lost in transit).

Voice Quality Metrics

MOS LQK

Score that is an objective estimate of the mean opinion score (MOS) for listening quality (LQK) that rates from 5 (excellent) to 1 (bad). This score is based on audible concealment events due to frame loss in the preceding 8-second interval of the voice stream. For more information, see Voice Quality Monitoring.

Note

The MOS LQK score can vary based on the type of codec that the Cisco Unified IP Phone uses.

Avg MOS LQK

Average MOS LQK score observed for the entire voice stream.

Min MOS LQK

Lowest MOS LQK score observed from start of the voice stream.

Max MOS LQK

Baseline or highest MOS LQK score observed from start of the voice stream.

These codecs provide the following maximum MOS LQK score under normal conditions with no frame loss:

- G.711 gives 4.5.

- G.722 gives 4.5.

- G.728/iLBC gives 3.9.

- G.729 A/AB gives 3.8.

Version of the Cisco proprietary algorithm used to calculate MOS LQK scores.

Cumulative Conceal Ratio

Total number of concealment frames divided by total number of speech frames received from start of the voice stream.

Interval Conceal Ratio

Ratio of concealment frames to speech frames in preceding 3-second interval of active speech. If using voice activity detection (VAD), a longer interval might be required to accumulate 3 seconds of active speech.

Max Conceal Ratio

Highest interval concealment ratio from start of the voice stream.

Conceal Secs

Number of seconds that have concealment events (lost frames) from the start of the voice stream (includes severely concealed seconds).

Severely Conceal Secs

Number of seconds that have more than 5 percent concealment events (lost frames) from the start of the voice stream.

Latency

(see note)

Estimate of the network latency, expressed in milliseconds. Represents a running average of the round-trip delay, measured when RTCP receiver report blocks are received.

Network Protocol

Identifies the current Network Protocol—IPv4.

Note

When the RTP Control Protocol is disabled, no data generates for this field and thus displays as 0.

To use a test tone, you must:

- Enable the tone generator

- Create a test tone

- Enable Tone Generator

- Create Test Tone

Enable Tone Generator

To enable the tone generator, follow these steps:

Procedure

Step 1

Verify that the phone is unlocked.

When options are inaccessible for modification, a locked padlock icon appears on the configuration menus. When options are unlocked and accessible for modification, an unlocked padlock icon appears on these menus.

To unlock or lock options on the Settings menu, press **# on the phone keypad. This action either locks or unlocks the options, depending on the previous state.

Note

If a Settings Menu password has been provisioned, SIP phones present an "Enter password" prompt after you enter **#.

Make sure to lock options after you have made your changes.

Caution

Do not press **#** to unlock options and then immediately press **#** again to lock options. The phone will interpret this sequence as **#**, which will reset the phone. To lock options after unlocking them, wait at least 10 seconds before you press **# again.

Step 2

While offhook, press Help twice to invoke the Call Statistics screen, or press Settings > Status > Call Statistics to invoke the Call Statistics screen.

Step 3

Look for the Tone softkey.

When the Tone softkey is visible, the softkey remains enabled for as long as this Cisco Unified IP phone is registered with Cisco Unified Communications Manager.

Step 4

If the Tone softkey is present, proceed to Create Test Tone.

Step 5

If the Tone softkey is not present, exit the Call Statistics screen and enter the Setting Menu.

Step 6

Press **3 on the phone keypad to enable (toggle) the Tone softkey.

Note

If you press **# **3 consecutively, with no pause, you will inadvertently reset the phone because of the **#** sequence.

Step 7

While offhook, press the Help button twice to invoke the Call Statistics screen, or press Settings > Status > Call Statistics to invoke the Call Statistics screen.

Step 8

Verify that the Tone softkey is present.

When the Tone softkey is visible, the softkey remains enabled for as long as this Cisco Unified IP Phone is registered with Cisco Unified Communications Manager.

Create Test Tone

Note

When measuring echo, make sure you first set the input and output levels to 0 dB gain/attenuation on the trunk. This is set for the gateway (in Cisco Unified Communications Manager for MGCP) or under IOS CLI for H.323 or SIP.

To create a test tone, follow these steps:

Procedure

Step 1

Place a call.

Step 2

After the call is established, press Help twice, or press Settings > Status > Call Statistics.

The Call Statistics screen and Tone softkey should appear.

Step 3

Press Tone.

The phone generates a 1004 Hz tone at -15 dBm.

- For a good network connection, the tone sounds at the call destination only.

- For a bad network connection, the phone generating the tone may receive echo from the destination phone.

Step 4

To stop the tone, end the call.

For information on interpreting the results of test tone for volume and echo, see Echo Analysis for Voice over IP.

Startup Problems

After installing a Cisco Unified IP Phone into your network and adding it to Cisco Unified Communications Manager, the phone should start up as described in Phone Startup Process. If the phone does not start up properly, see the following sections for troubleshooting information:

- Cisco Unified IP Phone Does Not Go Through Normal Startup Process

- Cisco Unified IP Phone Does Not Register with Cisco Unified Communications Manager

- Cisco Unified IP Phone Cannot Obtain IP Address

- Cisco Unified IP Phone Displays Security Error Message

Cisco Unified IP Phone Does Not Go Through Normal Startup Process

Problem

When you connect a Cisco Unified IP Phone into the network port, the phone should go through the normal startup process, and the LCD screen should display information.

Cause

If the phone does not go through the startup process, the cause may be faulty cables, bad connections, network outages, or lack of power. Or, the phone may not be functional.

Solution

To determine whether the phone is faulty, follow these suggestions to systematically eliminate these other potential problems:

1. Verify that the network port is functional:

- Exchange the Ethernet cables with cables that you know are functional.

- Connect a operational phone to this network port to verify the port is active.

- Replace an operational phone with the nonoperational phone.

- Connect the nonoperational phone directly to the port on the switch, eliminating the patch panel connection in the office.

2. Verify that the phone is receiving power:

- If you are using external power, verify that the electrical outlet is functional.

- If you are using in-line power, plug the phone into an electrical outlet using the external power supply.

- If you are using the external power supply, switch the power supply with a unit that you know works.

- Make sure that the phone is connected to a switch that supports IEEE 802.3af Class 3 (15.4 W in-line power at the switch port).

3. If the phone still does not start up properly, power up the phone with the handset off-hook. When the phone is powered up in this way, it attempts to launch a backup software image.

4. If the phone still does not start up properly, perform a factory reset of the phone.

If after attempting these solutions, the LCD screen on the Cisco Unified IP Phone does not display any characters after at least five minutes, contact a Cisco technical support representative for additional assistance.

Phone Startup Process

Cisco Unified IP Phone Power

Cisco Unified IP Phone Does Not Register with Cisco Unified Communications Manager

If the phone proceeds past the first stage of the startup process (LED buttons flashing on and off) but continues to cycle through the messages displaying on the LCD screen, the phone is not starting up properly. The phone cannot successfully start up unless it is connected to the Ethernet network and it has registered with a Cisco Unified Communications Manager server.

These sections can assist you in determining the reason the phone is unable to start up properly:

- Phone Displays Error Messages

- Phone Cannot Connect to TFTP Server or to Cisco Unified Communications Manager

- TFTP Server Settings

- IP Addressing and Routing

- DNS Settings

- Cisco Unified Communications Manager Settings on Phone

- Cisco CallManager and TFTP Services Are Not Running

- Configuration File Corruption

- Cisco Unified Communications Manager Phone Registration

Phone Displays Error Messages

Problem

Status messages display errors during startup.

Solution

As the phone cycles through the startup process, you can access status messages that might provide you with information about the cause of a problem. See Status Messages Screen for instructions about accessing status messages and for a list of potential errors, their explanations, and their solutions.

Phone Cannot Connect to TFTP Server or to Cisco Unified Communications Manager

Problem

If the network is down between the phone and either the TFTP server or Cisco Unified Communications Manager, the phone cannot start up properly.

Solution

Ensure that the network is currently running.

TFTP Server Settings

Problem

The TFTP server settings may not be correct.

Solution

Check the TFTP settings. See Check TFTP Settings.

IP Addressing and Routing

Problem

The IP addressing and routing fields may not be correctly configured.

Solution

You should verify the IP addressing and routing settings on the phone. If you are using DHCP, the DHCP server should provide these values. If you have assigned a static IP address to the phone, you must enter these values manually. See Check DHCP settings.

DNS Settings

Problem

The DNS settings may be incorrect.

Solution

If you are using DNS to refer to the TFTP server or to Cisco Unified Communications Manager, you must ensure that you have specified a DNS server. See Verify DNS Settings.

Cisco Unified Communications Manager Settings on Phone

Problem

The phone may have the wrong Cisco Unified Communications Manager information.

Solution

On the Cisco Unified IP Phone, press the Settings button, choose Device Configuration, and look at the Unified CM Configuration options. The Cisco Unified IP Phone attempts to open a TCP connection to all the Cisco Unified Communications Manager servers that are part of the assigned Cisco Unified Communications Manager group. If none of these options contain IP addresses or show Active or Standby, the phone is not properly registered with Cisco Unified Communications Manager. See Cisco Unified Communications Manager Phone Registration for tips on resolving this problem.

Cisco CallManager and TFTP Services Are Not Running

Problem

If the Cisco CallManager or TFTP services are not running, phones may not be able to start up properly. In such a situation, it is likely that you are experiencing a systemwide failure, and other phones and devices are unable to start up properly.

Solution

If the Cisco CallManager service is not running, all devices on the network that rely on it to make phone calls are affected. If the TFTP service is not running, many devices cannot start up successfully. For more information, see Start Service.

Configuration File Corruption

Problem

If you continue to have problems with a particular phone that other suggestions in this chapter do not resolve, the configuration file may be corrupted.

Solution

Create a new phone configuration file. See Create New Phone Configuration File.

Cisco Unified Communications Manager Phone Registration

Problem

The phone is not registered with Cisco Unified Communications Manager.

Solution

A Cisco Unified IP Phone can register with a Cisco Unified Communications Manager server only if the phone has been added to the server or if autoregistration is enabled. Review the information and procedures in Cisco Unified Communications Manager Phone Addition Methods to ensure that the phone has been added to the Cisco Unified Communications Manager database.

To verify that the phone is in the Cisco Unified Communications Manager database, choose Device > Phone > Find from Cisco Unified Communications Manager Administration to search for the phone based on the MAC Address. For information about determining a MAC address, see Cisco Unified IP Phone MAC Address Determination.

If the phone is already in the Cisco Unified Communications Manager database, its configuration file may be damaged. See Configuration File Corruption for assistance.

Cisco Unified IP Phone Cannot Obtain IP Address

Problem

If a phone cannot obtain an IP address when it starts up, the phone may not be on the same network or VLAN as the DHCP server, or the switch port to which the phone connects may be disabled.

Solution

Ensure that the network or VLAN to which the phone connects has access to the DHCP server, and ensure that the switch port is enabled.

Cisco Unified IP Phone Displays Security Error Message

Problem

The phone displays "Security Error" on the screen.

Cause

When a Cisco Unified IP Phone boots, it performs an internal Power On Self Test (POST). POST checks for existing encryption functionality. If POST detects that encryption functionality is missing, the phone fails to boot, and the message "Security Error" appears on the screen.

Solution

To correct the problem, perform the following steps:

1. Reset the phone manually.

2. If the phone does not start up properly, power up the phone with the handset off-hook. When the phone is powered up in this way, it attempts to launch a backup software image.

3. If the phone still does not start up properly, perform a factory reset of the phone. For instructions, see Factory Reset.

Cisco Unified IP Phone Resets Unexpectedly

If users report that their phones are resetting during calls or while idle on their desk, you should investigate the cause. If the network connection and Cisco Unified Communications Manager connection are stable, a Cisco Unified IP Phone should not reset on its own.

Typically, a phone resets if it has problems connecting to the Ethernet network or to Cisco Unified Communications Manager. These sections can help you identify the cause of a phone resetting in your network:

- Physical Connection Problems

- Intermittent Network Outages

- DHCP Setting Errors

- Static IP Address Setting Errors

- Voice VLAN Setup Errors

- Phones Have Not Been Intentionally Reset

- DNS or Other Connectivity Errors

- Power Connection Problems

Physical Connection Problems

Problem

The physical connection to the LAN may be broken.

Solution

Verify that the Ethernet connection to which the Cisco Unified IP Phone connects is up. For example, check whether the particular port or switch to which the phone connects is down and that the switch is not rebooting. Also ensure that no cable breaks exist.

Intermittent Network Outages

Problem

Your network may be experiencing intermittent outages.

Solution

Intermittent network outages affect data and voice traffic differently. Your network might be experiencing intermittent outages without detection. If so, data traffic can resend lost packets and verify that packets are received and transmitted. However, voice traffic cannot recapture lost packets. Rather than retransmitting a lost network connection, the phone resets and attempts to reconnect to the network. Contact the system administrator for information on known problems in the voice network.

DHCP Setting Errors

Problem

The DHCP settings may be incorrect.

Solution

The following suggestions can help you determine if the phone has been properly configured to use DHCP:

1. Verify that you have properly configured the phone to use DHCP. For more information, see Network Configuration Menu.

2. Verify that the DHCP server has been set up properly.

3. Verify the DHCP lease duration. Cisco recommends that you set it to 8 days.

Cisco Unified IP Phone 7971G-GE and 7970G send messages with request type 151 to renew their DHCP address leases. If the DHCP server expects messages with request type 150, the lease will be denied, forcing the Cisco Unified IP Phone 7971G-GE and 7970G to restart and request a new IP address from the DHCP server.

Static IP Address Setting Errors

Problem

The static IP address assigned to the phone may be incorrect.

Solution

If the phone has been assigned a static IP address, verify that you have entered the correct settings.

Voice VLAN Setup Errors

Problem

If the Cisco Unified IP Phone appears to reset during heavy network usage (for example, following extensive web surfing on a computer connected to same switch as phone), it is likely that you do not have a voice VLAN configured.

Solution

Isolating the phones on a separate auxiliary VLAN increases the quality of the voice traffic.

Phones Have Not Been Intentionally Reset

Problem

If you are not the only administrator with access to Cisco Unified Communications Manager, you should verify that no one else has intentionally reset the phones.

Solution

You can check whether a Cisco Unified IP Phone received a command from Cisco Unified Communications Manager to reset by pressing the Applications Menu button on the phone and choosing Settings > Status > Network Statistics. If the phone was recently reset one of these messages appears:

- Reset-Reset: Phone received a Reset-Reset request from Cisco Unified Communications Manager Administration.

- Reset-Restart: Phone received a Reset-Restart request from Cisco Unified Communications Manager Administration.

DNS or Other Connectivity Errors

Problem

The phone reset continues and you suspect DNS or other connectivity issues.

Solution

If the phone continues to reset, eliminate DNS or other connectivity errors with Determine DNS or Connectivity Issues.

Power Connection Problems

Problem

The phone does not appear to be powered up.

Solution

In most cases, a phone restarts if it powers up by using external power but loses that connection and switches to PoE. Similarly, a phone may restart if it powers up by using PoE and then connects to an external power supply.

After a reset, the phone does not authenticate.

Cause

These errors typically indicate that the phone has completed a factory reset (see Factory Reset) while 802.1X was enabled. A factory reset deletes the shared secret, which is required for 802.1X authentication and network access.

Solution

To resolve this, you have two options:

- Temporarily disable 802.1X authentication on the switch.

- Temporarily move the phone to a network environment that is not using 802.1X authentication.

Once the phone starts up normally in one of these conditions, you can access the 802.1X configuration menus and re-enter the shared secret (see 802.1X Authentication and Status Menus).

Audio and Video Problems

The following sections describe how to resolve audio and video problems.

- Phone Display Is Wavy

- No Speech Path

Phone Display Is Wavy

Problem

The display appears to have rolling lines or a wavy pattern.

Cause

The phone might be interacting with certain types of older fluorescent lights in the building.

Solution

Move the phone away from the lights or replace the lights to resolve the problem.

No Speech Path

Problem

One or more people on a call do not hear any audio.

Solution

When at least one person in a call does not receive audio, IP connectivity between phones is not established. Check the configuration of routers and switches to ensure that IP connectivity is properly configured.

General Telephone Call Problems

This section describes troubleshooting of general telephone call problems.

- VPN-Connected Phone Does Not Log Calls

- Phone Does Not Recognize DTMF Digits or Digits Are Delayed

VPN-Connected Phone Does Not Log Calls

Problem

A remote location (home office) phone that is connected through the VPN does not log missed, placed, or received calls.

Cause

Without explicitly setting the Alternate TFTP setting, the Cisco IP Phone cannot contact the TFTP server and download the configuration and other files, and function properly.

Solution

Set up the phone to use the Alternate TFTP server and configure the TFTP server IP address.

Related Tasks

Set Up Remote Phone

Phone Does Not Recognize DTMF Digits or Digits Are Delayed

Problem

The user complains that numbers are missed or delayed when the keypad is used.

Cause

Pressing the keys too quickly can result in missed or delayed digits.

Solution

Keys should not be pressed rapidly.

Troubleshooting Procedures

These procedures can be used to identify and correct problems.

- Set Up Remote Phone

- Check TFTP Settings

- Check DHCP settings

- Verify DNS Settings

- Create New Phone Configuration File

- Start Service

- Determine DNS or Connectivity Issues

Set Up Remote Phone

Cisco IP Phones that are configured for SSL VPN to ASA using the built-in client in a remote location (for example, a home office) have a special configuration requirement.

We recommend that you provide the phone with an Alternate TFTP server setting manually. This setting allows the phone to download the configuration and other files from TFTP. The phone in a remote location (home office) cannot correctly provide OPTION 150 to the phone using DHCP.

The IP phone can register to the last-known Cisco Unified Communications Manager, but any configuration updates cannot applied until you configure the manual TFTP server address.

Procedure

Step 1

On the phone, select Applications.

Step 2

Navigate to the IPv4 Settings window.

Step 3

Scroll to the Alternate TFTP option and set the field to Yes.

Step 4

In the TFTP Server 1 field, set the TFTP server address.

Step 5

Save the changes.

Check TFTP Settings

Procedure

Step 1

You can determine the IP address of the TFTP server used by the phone by pressing the Settings button on the phone, choosing Network Configuration > IPv4, and scrolling to the TFTP Server 1 option.

Step 2

If you have assigned a static IP address to the phone, you must manually enter a setting for the TFTP Server 1 option. See Network Configuration Menu.

Step 3

If you are using DHCP, the phone obtains the address for the TFTP server from the DHCP server. Check the IP address configured in Option 150.

Step 4

You can also enable the phone to use an alternate TFTP server. Such a setting is particularly useful if the phone was recently moved from one location to another. See Network Configuration Menu for instructions.

Check DHCP settings

Procedure

Step 1

On the Cisco Unified IP Phone, press the Settings button, choose Network Configuration, and look at the following options:

- DHCP Server: If you have assigned a static IP address to the phone, you do not need to enter a value for the DHCP Server option. However, if you are using a DHCP server, this option must have a value. If it does not, check your IP routing and VLAN configuration. See Troubleshooting Switch Port Problems at this URL: http://www.cisco.com/en/US/products/hw/switches/ps708/prod_tech_notes_list.html

- IP Address, Subnet Mask, Default Router: If you have assigned a static IP address to the phone, you must manually enter settings for these options. See Network Configuration Menu for instructions.

Step 2

If you are using DHCP, check the IP addresses distributed by your DHCP server. See Understanding and Troubleshooting DHCP in Catalyst Switch or Enterprise Networks at this URL: http://www.cisco.com/en/US/tech/tk648/tk361/technologies_tech_note09186a00800f0804.shtml

Verify DNS Settings

To verify DNS settings, perform these steps.

Procedure

Step 1

Verify this setting by pressing Settings.

Step 2

Choose Network Configuration and scroll to the DNS Server 1 option.

Step 3

Verify that a CNAME entry exists in the DNS server for the TFTP server and for the Cisco Unified Communications Manager system.

Step 4

Ensure that DNS is configured to do reverse look-ups.

Create New Phone Configuration File

If you continue to have problems with a particular phone that other suggestions in this chapter do not resolve, the configuration file may be corrupted.

Note

- When you remove a phone from the Cisco Unified Communications Manager database, the configuration file is deleted from the Cisco Unified Communications Manager TFTP server. The phone directory number or numbers remain in the Cisco Unified Communications Manager database. They are called "unassigned DNs" and can be used for other devices. If unassigned DNs are not used by other devices, delete them from the Cisco Unified Communications Manager database. You can use the Route Plan Report to view and delete unassigned reference numbers. See the Cisco Unified Communications Manager Administration Guide for more information.

- Changing the buttons on a phone button template, or assigning a different phone button template to a phone, may result in directory numbers that are no longer accessible from the phone. The directory numbers are still assigned to the phone in the Cisco Unified Communications Manager database, but the phone has no button with which calls can be answered. These directory numbers should be removed from the phone and deleted if necessary.

To create a new configuration file, follow these steps:

Procedure

Step 1

From Cisco Unified Communications Manager, choose Device > Phone > Find to locate the phone experiencing problems.

Step 2

Choose Delete to remove the phone from the Cisco Unified Communications Manager database.

Step 3

Add the phone back to the Cisco Unified Communications Manager database. See Cisco Unified Communications Manager Phone Addition Methods for details.

Step 4

Power cycle the phone.

Start Service

Note

A service must be activated before it can be started or stopped. To activate a service, choose Tools > Service Activation.

To start a service, follow these steps:

Procedure

Step 1

From Cisco Unified Communications Manager Administration, choose Cisco Unified Serviceability from the Navigation drop-down list and click Go.

Step 2

Choose Tools > Control Center - Feature Services.

Step 3

Choose the primary Cisco Unified Communications Manager server from the Server drop-down list.

The window displays the service names for the server that you chose, the status of the services, and a service control panel to start or stop a service.

Step 4

If a service has stopped, click the corresponding radio button and then click Start.

The Service Status symbol changes from a square to an arrow.

Determine DNS or Connectivity Issues

If the phone continues to reset, follow these steps to eliminate DNS or other connectivity errors:

Procedure

Step 1

Use the Erase softkey to reset phone settings to their default values. See Cisco Unified IP Phone Reset or Restore for details.

Step 2

Modify DHCP and IP settings:

1. Disable DHCP. See Network Configuration Menu for instructions.

2. Assign static IP values to the phone. See Network Configuration Menu for instructions. Use the same default router setting used for other functioning Cisco Unified IP Phones.

3. Assign TFTP server. See Network Configuration Menu for instructions. Use the same TFTP server used for other functioning Cisco Unified IP Phones.

Step 3

On the Cisco Unified Communications Manager server, verify that the local host files have the correct Cisco Unified Communications Manager server name mapped to the correct IP address.

Step 4

From Cisco Unified Communications Manager, choose System > Server and verify that the server is referred to by the IP address and not by its DNS name.

Step 5

From Cisco Unified Communications Manager, choose Device > Phone and verify that you have assigned the correct MAC address to this Cisco Unified IP Phone. For information about determining a MAC address, see Cisco Unified IP Phone MAC Address Determination.

Step 6

Power cycle the phone.

General Troubleshooting Information

The following table provides general troubleshooting information for the Cisco Unified IP Phone.

Cisco Unified IP Phone Troubleshooting

Summary

Explanation

Daisy-chaining IP phones

Cisco does not support connecting an IP phone to another IP phone through the PC port. Each IP phone should directly connect to a switch port. If phones are connected together in a line (by using the PC port), the phones do not work.

Poor quality when calling mobile phones using the G.729 protocol

In Cisco Unified Communications Manager, you can configure the network to use the G.729 protocol (the default is G.711). When using G.729, calls between an IP phone and a mobile phone will have poor voice quality. Use G.729 only when absolutely necessary.

Prolonged broadcast storms cause IP phones to reset, or be unable to make or answer a call

A prolonged Layer 2 broadcast storm (lasting several minutes) on the voice VLAN may cause IP phones to reset, lose an active call, or be unable to initiate or answer a call. Phones may not come up until a broadcast storm ends.

Moving a network connection from the phone to a workstation

If you are powering your phone through the network connection, you must be careful if you decide to unplug the phone network connection and plug the cable into a desktop computer.

Caution

The computer network card cannot receive power through the network connection; if power comes through the connection, the network card can be destroyed. To protect a network card, wait 10 seconds or longer after unplugging the cable from the phone before plugging it into a computer. This delay gives the switch enough time to recognize that no phone is on the line and to stop providing power to the cable.

Changing the telephone configuration

By default, the network configuration options are locked to prevent users from making changes that could impact their network connectivity. You must unlock the network configuration options before you can configure them. See Unlock and Lock Options for details.

Codec mismatch between the phone and another device

The RxType and the TxType statistics show the codec that is used for a conversation between this Cisco Unified IP Phone and the other device. The values of these statistics should match. If they do not, verify that the other device can handle the codec conversation or that a transcoder is in place to handle the service.

See Call Statistics Screen for information about displaying these statistics.

Sound sample mismatch between the phone and another device

The RxSize and the TxSize statistics show the size of the voice packets that are used in a conversation between this Cisco Unified IP phone and the other device. The values of these statistics should match.

See Call Statistics Screen for information about displaying these statistics.

Gaps in voice calls

Check the AvgJtr and the MaxJtr statistics. A large variance between these statistics might indicate a problem with jitter on the network or periodic high rates of network activity.

See Call Statistics Screen for information about displaying these statistics.

Loopback condition

A loopback condition can occur when the following conditions are met:

- The SW Port Configuration option in the Network Configuration menu on the phone is set to 10 Half(10-BaseT/half duplex).

- The phone receives power from an external power supply.

- The phone is powered down (the power supply is disconnected).

In this case, the switch port on the phone can become disabled and the following message will appear in the switch console log:

HALF_DUX_COLLISION_EXCEED_THRESHOLD

To resolve this problem, re-enable the port from the switch.

Peer to peer image distribution fails.

If the peer to peer image distribution fails, the phone will default to using the TFTP server to download firmware. Access the log messages stored on the remote logging machine to help debug the peer to peer image distribution feature.

Note

These log messages are different than the log messages sent to the phone log.

Cisco VT Advantage/ Unified Video Advantage (CVTA)

If you are having problems getting CVTA to work, make sure that the PC Port is enabled, and that CDP is enabled on the PC port.

Phone call cannot be established

The phone does not have a DHCP IP address, is unable to register to Cisco Unified Communications Manager, and shows a Configuring IP or Registering message.

Verify the following:

1. The Ethernet cable is attached.

2. The Cisco CallManager service is running on the Cisco Unified Communications Manager server.

3. Both phones are registered to the same Cisco Unified Communications Manager.

4. Audio server debug and capture logs are enabled for both phones. If needed, enable Java debug.

Call established with the iLBC protocol does not show that the iLBC codec is being used

Call statistics display does not show iLBC as the receiver/sender codec.

1. Check the following by using Cisco Unified Communications Manager Administration:

- Both phones are in the iLBC device pool.

- The iLBC device pool is configured with the iLBC region.

- The iLBC region is configured with the iLBC codec.

2. Capture a sniffer trace between the phone and Cisco Unified Communications Manager and verify that SCCP messages, OpenReceiveChannel, and StationMediaTransmit messages have media payload type value equal to 86. If so, the problem is with the phone; otherwise, the problem is with the Cisco Unified Communications Manager configuration.

3. Enable audio server debug and capture logs from both phones. If needed, enable Java debug.

Cisco Unified IP Phone Reset or Restore

Two methods exist for resetting or restoring the Cisco Unified IP Phone:

- Basic Reset

- Factory Reset

Basic Reset

Performing a basic reset of a Cisco Unified IP Phone provides a way to recover if the phone experiences an error and provides a way to reset or restore various configuration and security settings.

The following table describes the ways to perform a basic reset. You can reset a phone with any of these operations any time after the phone has started up. Choose the operation that is appropriate for your situation.

Basic Reset Methods

Operation

Performing

Explanation

Restart phone

From the Main screen, press Settings to display the Settings menu, then press **#**.

Note

This factory reset sequence also works from any other screen that does not accept user input.

Resets any user and network configuration changes that you have made but that the phone has not written to the flash memory to previously saved settings, then restarts the phone.

Erase softkey

From the Settings menu, unlock phone options (see Unlock and Lock Options). Then press Erase.

Resets user and network configuration settings to their default values, deletes the CTL file from the phone, and restarts the phone.

From the Network Configuration menu, unlock phone options (see Unlock and Lock Options). Then press Erase.

Resets network configuration settings to their default values and resets the phone. (This method causes DHCP reconfigure the IP address of the phone.)

From the Security Configuration menu, unlock phone options (see Unlock and Lock Options). Then press the Erase softkey.

Deletes the CTL file from the phone and restarts the phone.

Factory Reset

When you perform a factory reset of the Cisco Unified IP Phone, the following information is erased or reset to its default value:

- CTL file: Erased

- LSC: Erased

- User configuration settings: Reset to default values

- Network configuration settings: Reset to default values

- Call histories: Erased

- Locale information: Reset to default values

- Phone application: Erased (phone recovers by loading the appropriate default load file, which depends on the phone model term75.default.loads, term71.default.loads, term70.default.loads, term65.default.loads, or term45.default.loads)

Before you perform a factory reset, ensure that the following conditions are met:

- The phone must be on a DHCP-enabled network.

- A valid TFTP server must be set in DHCP option 150 or option 66 on the DHCP server.

- The default load file for your phone model and the files specified in that file should be available on the TFTP server that is specified by the DHCP packet.

To perform a factory reset of a phone, follow these steps:

Procedure

Step 1

Unplug the power cable from the phone and then plug it back in.

The phone begins the power-up cycle.

Step 2

While the phone is powering up, and before the Speaker button flashes on and off, press and hold #.

Continue to hold # until each line button flashes on and off in sequence in orange (for the Cisco Unified IP Phone 7975G, 7971G-GE and 7970G) or amber (for the Cisco Unified IP Phone 7965G and 7945G).

Step 3

Release # and press 123456789*0#.

You can press a key twice in a row, but if you press the keys out of sequence, the factory reset does not take place.

After you press these keys, the line buttons on the phone flash orange and then green (for the Cisco Unified IP Phone 7975G, 7971G-GE and 7970G) or red (for the Cisco Unified IP Phone 7965G and 7945G), and the phone goes through the factory reset process. This process can take several minutes.

Do not power down the phone until it completes the factory reset process, and the main screen displays.

Maintenance

This section contains the following topics

- Quality Report Tool

- Voice Quality Monitoring

- Cisco Unified IP Phone Cleaning

Quality Report Tool

The Quality Report Tool (QRT) is a voice quality and general problem-reporting tool for the Cisco Unified IP Phone. The QRT feature is installed as part of the Cisco Unified Communications Manager installation.

You can configure Cisco Unified IP Phones with QRT. When you do so, users can report problems with phone calls pressing QRT. This softkey is available only when the Cisco Unified IP Phone is in the Connected, Connected Conference, Connected Transfer, or OnHook states.

When a user presses QRT, a list of problem categories appears. The user selects the appropriate problem category, and this feedback is logged in an XML file. Actual information logged depends on the user selection, and if the destination device is a Cisco Unified IP Phone.

For more information about using QRT, see the Cisco Unified Serviceability Administration Guide.

Voice Quality Monitoring

To measure the voice quality of calls that are sent and received within the network, Cisco Unified IP Phones use these statistical metrics based on concealment events. The Digital Signal Processor (DSP) plays concealment frames to mask frame loss in the voice packet stream.

- Concealment Ratio metrics: Show the ratio of concealment frames over total speech frames. An interval conceal ratio is calculated every 3 seconds.

- Concealed Second metrics: Show the number of seconds in which the DSP plays concealment frames due to lost frames. A severely "concealed second" is a second in which the DSP plays more than five percent concealment frames.

- MOS-LQK metrics: Use a numeric score to estimate the relative voice listening quality. The Cisco Unified IP Phone calculates the mean opinion score (MOS) for listening quality (LQK) based audible concealment events due to frame loss in the preceding 8 seconds, and includes perceptual weighting factors such as codec type and frame size.

MOS LQK scores are produced by a Cisco proprietary algorithm, Cisco Voice Transmission Quality (CVTQ) index. Depending on the MOS LQK version number, these scores might be compliant with the International Telecommunications Union (ITU) standard P.564. This standard defines evaluation methods and performance accuracy targets that predict listening quality scores based on observation of actual network impairment.

Note

Concealment ratio and concealment seconds are primary measurements based on frame loss while MOS LQK scores project a "human-weighted" version of the same information on a scale from 5 (excellent) to 1 (bad) for measuring listening quality.

Listening quality scores (MOS LQK) relate to the clarity or sound of the received voice signal. Conversational quality scores (MOS CQ such as G.107) include impairment factors, such as delay, that degrade the natural flow of conversation.

You can access voice quality metrics from the Cisco Unified IP Phone by using the Call Statistics screen (see Call Statistics Screen) or remotely by using Streaming Statistics (see Remote Monitoring).

- Voice Quality Metric Interpretation

- Voice Quality Troubleshooting Tips

Voice Quality Metric Interpretation

To use the metrics for monitoring voice quality, note the typical scores under normal conditions of zero packet loss and use the metrics as a baseline for comparison.

It is important to distinguish significant changes from random changes in metrics. Significant changes are scores that change about 0.2 MOS or greater and persist in calls that last longer than 30 seconds. Conceal Ratio changes should indicate greater than 3 percent frame loss.

MOS LQK scores can vary based on the codec that the Cisco Unified IP Phone uses. The following codecs provide these maximum MOS LQK scores under normal conditions with zero frame loss:

- For Cisco Unified Phone 7975G, 7965G, and 7945G:

- G.711 gives 4.5 score.

- G.722 gives 4.5.

- G.728/iLBC gives 3.9.

- G.729A/AB gives 3.8.

- For Cisco Unified Phone 7971G-GE and 7970G:

- G.711 codec gives 4.5 score.

- G.729A/AB gives 3.7.

Note

- CVTQ does not support wideband (7 kHz) speech codecs, as ITU has not defined the extension of the technique to wideband. Therefore, MOS scores that correspond to G.711 performance are reported for G.722 calls to allow basic quality monitoring, rather than not reporting an MOS score.

- Reporting G.711-scale MOS scores for wideband calls through the use of CVTQ allows basic quality classifications to be indicated as good/normal or bad/abnormal. Calls with high scores (approximately 4.5) indicate high quality/low packet loss, and lower scores (approximately 3.5) indicate low quality/high packet loss.

- Unlike MOS, the Conceal Ratio and Concealed Seconds metrics remain valid and useful for both wideband and narrowband calls.

A Conceal Ratio of zero indicates that the IP network is delivering frames and packets on time with no loss.

Voice Quality Troubleshooting Tips

When you observe significant and persistent changes to metrics, use the following table for general troubleshooting information:

Changes to Voice Quality Metrics

Metric change

Condition

MOS LQK scores decrease significantly

Network impairment from packet loss or high jitter:

- Average MOS LQK decreases could indicate widespread and uniform impairment.

- Individual MOS LQK decreases indicate bursty impairment.

Cross-check with Conceal Ratio and Conceal Seconds for evidence of packet loss and jitter.

MOS LQK scores decrease significantly

Check to see whether the phone is using a different codec than expected (RxType and TxType).

Check to see whether the MOS LQK version changed after a firmware upgrade.

Conceal Ratio and Conceal Seconds increase significantly

- Network impairment from packet loss or high jitter.

Conceal Ratio is near or at zero, but the voice quality is poor.

Noise or distortion in the audio channel such as echo or audio levels.

Tandem calls that undergo multiple encode/decode, such as calls to a cellular network or calling card network.

Acoustic problems coming from a speakerphone, handsfree cellular phone, or wireless headset.

Check packet transmit (TxCnt) and packet receive (RxCnt) counters to verify that voice packets are flowing.

Note

Voice quality metrics do not account for noise or distortion, only frame loss.

Cisco Unified IP Phone Cleaning

To clean your Cisco Unified IP phone, use a soft, dry cloth to wipe the phone screen. Do not apply liquids or powders directly on the phone. As with all non-weather-proof electronics, liquids and powders can damage the components and cause failures.

Disable the screen before cleaning it so that you will not inadvertently choose a feature from the pressure of the cleaning cloth. To disable the screen, press Display for more than one second. The phone displays Touchscreen Disabled or Phone Screen Disabled and the Display button flashes green.

After one minute, the screen automatically reenables itself. To reenable the screen before that, press the flashing Display button for more than one second. The phone displays Touchscreen Enabled or Phone Screen Enabled.

- Unified Communications Manager Endpoints Locale Installer

- Language Limitation

- International Call Logging Support

International User Support Overview

Translated and localized versions of the Cisco Unified IP Phones are available in several languages. If you are supporting Cisco Unified IP Phones in a non-English environment, the following sections ensure that the phones are set up properly for your users.

Language Overlays for Phone Buttons

To support the needs of international users, the button labels on the Cisco Unified IP Phones display icons rather than text to indicate the purposes of the buttons. You can purchase language-specific text overlays to add to a phone. To order these language-specific overlays, go to this website:

http://www.overlaypro.com/cisco/

Phone overlays are available only for languages in which the Cisco Unified IP Phone software has been localized. All languages may not be available immediately, so continue to check the website for updates.

Unified Communications Manager Endpoints Locale Installer

By default, Cisco IP Phones are set up for the English (United States) locale. To use the Cisco IP Phones in other locales, you must install the locale-specific version of the Unified Communications Manager Endpoints Locale Installer on every Cisco Unified Communications Manager server in the cluster. The Locale Installer installs the latest translated text for the phone user interface and country-specific phone tones on your system so that they are available for the Cisco IP Phones.

To access the Locale Installer required for a release, access https://software.cisco.com/download/navigator.html?mdfid=286037605&flowid=46245, navigate to your phone model, and select the Unified Communications Manager Endpoints Locale Installer link.

For more information, see the documentation for your particular Cisco Unified Communications Manager release.

Note

The latest Locale Installer may not be immediately available; continue to check the website for updates.

Language Limitation

There is no localized Keyboard Alphanumeric Text Entry (KATE) support for the following Asian locales:

- Chinese (China)

- Chinese (Hong Kong)

- Chinese (Taiwan)

- Japanese (Japan)

- Korean (Korea Republic)

The default English (United States) KATE is presented to the user instead.

For example, the phone screen will show text in Korean, but the 2 key on the keypad will display a b c 2 A B C.

International Call Logging Support

If your phone system is configured for international call logging (calling party normalization), the call logs, redial, or call directory entries may display a plus (+) symbol to represent the international escape code for your location. Depending on the configuration for your phone system, the + may be replaced with the correct international dialing code, or you may need to edit the number before dialing to manually replace the + with the international escape code for your location. In addition, while the call log or directory entry may display the full international number for the received call, the phone display may show the shortened local version of the number, without international or country codes.

- Phone Setup

- Perform Final End User Setup

Phone Administration Overview

This appendix provides minimum, basic configuration steps for you to perform the following actions:

- Add a new user to Cisco Unified Communications Manager Administration

- Configure a new phone for that user

- Associate that user to that phone

- Complete other basic end-user configuration tasks

The procedures provide one method for performing these tasks and are not the only way to perform these tasks. They are a streamlined approach to get a new user and corresponding phone running on the system.

These procedures are designed to be used on a mature Cisco Unified Communications Manager system where calling search spaces, partitions, and other complicated configuration have already been done and are in place for existing users.

Example User Information

In the procedures that follow, examples are given when possible to illustrate some of the steps. Example user and phone information used throughout these procedures includes:

- User’s Name: John Doe

- User ID: johndoe

- MAC address listed on phone: 00127F576611

- Five-digit internal telephone number: 26640

Cisco Unified Communications Manager User Addition

This section describes steps for adding a user to Cisco Unified Communications Manager. Follow one of the procedures in this section, depending on your operating system and the manner in which you are adding the user:

- Add User from External LDAP Directory

- Add User Directly to Cisco Unified Communications Manager

Add User from External LDAP Directory

For more information and limitations on configuring LDAP system, see the Cisco Unified Communications Manager Administration Guide, "LDAP System Configuration", "LDAP Directory Configuration", and the "LDAP Authentication Configuration" chapters and Cisco Unified Communications Manager System Guide, "Understanding the Directory" chapter.

If you added a user to an LDAP Directory (a non-Cisco Unified Communications Server directory), you can immediately synchronize that directory to the Cisco Unified Communications Manager on which you are adding this same user and the user phone by following these steps:

Procedure

Step 1

Log onto Cisco Unified Communications Manager Administration.

Step 2

Choose System > LDAP > LDAP Directory.

Step 3

Use the Find button to locate your LDAP directory.

Step 4

Click on the LDAP directory name.

Step 5

Click Perform Full Sync Now.

Note

If you do not need to immediately synchronize the LDAP Directory to Cisco Unified Communications Manager, the LDAP Directory Synchronization Schedule on the LDAP Directory window determines when the next autosynchronization occurs. However, the synchronization must occur before you can associate a new user to a device.

Step 6

Proceed to Phone Setup.

Add User Directly to Cisco Unified Communications Manager

If you are not using an LDAP directory, you can add a user directly to Cisco Unified Communications Manager Administration by following these steps:

Procedure

Step 1

Choose User Management > End User, then click Add New. The End User Configuration window appears.

Step 2

In the User Information pane of this window, enter the following:

- User ID: Enter the user identification name. Cisco Unified Communications Manager does not permit modifying the user ID after it is created. You may use the following special characters: =, +, <, >, #, ;, \, , "", and blank spaces.

Example: johndoe

- Password and Confirm Password: Enter five or more alphanumeric or special characters for the end user password. You may use the following special characters: =, +, <, >, #, ;, \, , "", and blank spaces.

- Last Name: Enter the user last name. You may use the following special characters: =, +, <, >, #, ;, \, , "", and blank spaces.

Example: doe

- Telephone Number: Enter the primary directory number for the user. End users can have multiple lines on their phones.

Example: 26640 (John Doe’s internal company telephone number)

Step 3

Click Save.

Step 4

Proceed to the section Phone Setup.

Phone Setup

To configure the phone, you must first identify the phone and then configure using the following procedures.

- Identify Phone

- Set Up Phone Fields

Identify Phone

To identify the user phone model and protocol, follow these steps:

Procedure

Step 1

From Cisco Unified Communications Manager administration, choose Device > Phone.

Step 2

Click Add New.

Step 3

Select the user phone model from the Phone Type drop-down list, then click Next.

Step 4

Select the device protocol (SCCP or SIP) from the drop-down list, then click Next. The Phone Configuration window appears.

Set Up Phone Fields

On the Phone Configuration window, you can use the default values for most of the fields.

To configure the required fields and some key additional fields, follow these steps:

Procedure

Step 1

For the required fields, possible values, some of which are based on the example of user johndoe, can be configured as follows:

1. In the Device Information pane of this window:

- MAC Address: Enter the MAC address of the phone, which is listed on a sticker on the phone.

The MAC address is 12 hexadecimal characters long.

Example: 00127F576611 (MAC address on John Doe’s phone)

- Description: This is an optional field in which you can enter a useful description, such as John Doe’s phone. This will help you if you need to search on information about this user.

- Device Pool: Choose the device pool to which you want this phone assigned. The device pool defines sets of common characteristics for devices, such as region, date/time group, softkey template, and MLPP information.

Note

Device Pools are defined on the Device Pool Configuration window of Cisco Unified Communications Server Administration (System > Device Pool).

- Phone Button Template: Choose the appropriate phone button template from the drop-down list. The phone button template determines the configuration of buttons on a phone and identifies which feature is used for each button.

Note

Phone button templates are defined on the Phone Button Template Configuration window of Cisco Unified Communications Manager Administration (Device > Device Settings > Phone Button Template). You can use the search fields in conjunction with the Find button to find all configured phone button templates and their current settings.

- Softkey Template: Choose the appropriate softkey template. The softkey template determines the configuration of the softkeys on Cisco Unified IP Phones. Leave this field blank if the common device configuration contains the assigned softkey template.

Note

Softkey templates are defined on the Softkey Template Configuration window of Cisco Unified Communications Manager Administration (Device > Device Settings > Softkey Template). You can use the search fields in conjunction with the Find button to find all configured softkey templates and their current settings.

- Common Phone Profile: From the drop-down list box, choose a common phone profile from the list of available common phone profiles.

Note

Common Phone Profiles are defined on the Common Phone Profile Configuration window of Cisco Unified Communications Manager Administration (Device > Device Settings > Common Phone Profile). You can use the search field in conjunction with the Find button to find all configured common phone profiles and their current settings.

- Calling Search Space: From the drop-down list box, choose the appropriate calling search space (CSS). A calling search space comprises a collection of partitions (analogous to a collection of available phone books) that are searched to determine how a dialed number should be routed. The calling search space for the device and the calling search space for the directory number get used together. The directory number CSS takes precedence over the device CSS.

Note

Calling Search Spaces are defined on the Calling Search Space Configuration window of Cisco Unified Communications Manager Administration (Calling routing > Class of Control > Calling Search Space). You can use the search fields in conjunction with the Find button to find all configured Calling Search Spaces and their current settings.

- Location: Choose the appropriate location for this Cisco Unified IP Phone.

- Owner User ID: From the drop-down menu, choose the user ID of the assigned phone user.

2. In the Protocol Specific Information pane of this window, choose a Device Security Profile from the drop-down list. To enable security features for a phone, you must configure a new security profile for the device type and protocol and apply it to the phone. If the phone does not support security, choose a nonsecure profile.

To identify the settings that are contained in the profile, choose System > Security Profile > Phone Security Profile.

Note

The security profile chosen should be based on the overall security strategy of the company.

3. Also in the Protocol Specific Information pane of this window, choose the applicable SIP Profile from the drop-down list for SIP phones.

4. In the Extension Information pane of this window, check the Enable Extension Mobility box if this phone supports Cisco Extension Mobility.

5. In the Product Specific Configuration Layout pane of this window, enable the Video Capabilities field if this field appears on your window.

6. Click Save.

Step 2

Configure line settings:

1. On the Phone Configuration window, click Line 1 on the left pane of the window. The Directory Number Configuration window appears.

2. In the Directory Number field, enter a valid number that can be dialed.

Note

This field should contain the same number that appears in the Telephone Number field on the User Configuration window.

Example: 26640 is the directory number of user John Doe in the example above.

3. From the Route Partition drop-down list, choose the partition to which the directory number belongs. If you do not want to restrict access to the directory number, choose <None> for the partition.

4. From the Calling Search Space drop-down list (Directory Number Settings pane of the Directory Number Configuration window), choose the appropriate calling search space. A calling search space comprises a collection of partitions that are searched for numbers that are called from this directory number. The value that you choose applies to all devices that are using this directory number.

5. In the Call Pickup and Call Forward Settings pane of the Directory Number Configuration window, choose the items (for example, Forward All, Forward Busy Internal) and corresponding destinations to which calls should be sent.

Example: If you want incoming internal and external calls that receive a busy signal to be forwarded to the voice mail for this line, check the Voice Mail box next to the "Forward Busy Internal" and "Forward Busy External" items in the left column of the Call Pickup and Call Forward Settings pane.

6. In the "Line 1 on Device..." pane of the Directory Number Configuration window, configure the following fields:

- Display (Internal Caller ID field): You can enter the first name and last name of the user of this device so that this name is displayed for all internal calls. You can also leave this field blank to have the system display the phone extension.
