Phone Overview

The Cisco Unified IP Phone 6901 and 6911 provides voice communication over an Internet Protocol (IP) network. The Cisco Unified IP Phone functions much like a digital business phone, allowing you to place and receive phone calls. The Cisco Unified IP Phones in this guide have the following attributes:

- Cisco Unified IP Phone 6901 supports basic features such as hold, redial, transfer, and conference.

- Cisco Unified IP Phone 6911 supports advanced features such as mute, hold, transfer, conference, speed dial, call forward, and more.

A Cisco Unified IP  Phone, like other network devices, must be configured and managed. These phones encode G.711a, G.711mu, G.729a, G.729ab, and iLBC codecs, and decode G.711a, G.711mu, G.729, G.729ab, and iLBC codecs. These phones encode and decode the codecs in similar manner.

Caution

Using 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, refer to the manufacturer’s documentation of the interfering device.

For more information, see the Cisco Unified IP Phone 6901 and 6911 User Guide for Cisco Unified Communications Manager (SCCP and SIP).

Important Headset Safety Information

High Sound Pressure—Avoid listening to high volume levels for long periods to prevent possible hearing damage.

When you plug in your headset, lower the volume of the headset speaker before you put the headset on. If you remember to lower the volume before you take the headset off, the volume will start lower when you plug in your headset again.

Be aware of your surroundings. When you use your headset, it may block out important external sounds, particularly in emergencies or in noisy environments. Don’t use the headset while driving. Don’t leave your headset or headset cables in an area where people or pets can trip over them. Always supervise children who are near your headset or headset cables.

Network Protocols

Cisco Unified IP Phones support several industry-standard and Cisco network protocols required for voice communication. The following table provides an overview of the network protocols that the Cisco Unified IP Phone 6901 and 6911 support.

Supported Network Protocols on the Cisco Unified IP Phone

Network Protocol

Purpose

Usage notes

Cisco Audio Session Tunneling (CAST)

(Cisco Unified IP Phone 6911 only)

The CAST protocol allows IP Phones and associated applications behind the phone to discover and communicate with the remote endpoints without requiring changes to the traditional signaling components like Cisco Unified Communications Manager and gateways. The CAST protocol allows separate hardware devices to synchronize related media and it allows PC applications to augment nonvideo-capable phones to become video enabled by using the PC as the video resource.

-

Cisco Discovery Protocol (CDP)

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

Using CDP, a device advertises its existence to other devices and receives 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.

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 needing to manually assign an IP address or to configure additional network parameters.

By default, the phone has DHCP enabled. 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, go to the "Dynamic Host Configuration Protocol" chapter and the "Cisco TFTP" chapter in the Cisco Unified Communications Manager System Guide.

Note

If you cannot use option 150, you may try using DHCP option 66.

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 troubleshooting purposes.

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

The Cisco Unified IP Phone implements the IEEE 802.1X standard by providing support for the following authentication methods: EAP-FAST and EAP-TLS.

When 802.1X authentication is enabled on the phone, you should disable the voice VLAN. Refer to the 802.1X Authentication for additional information.

Internet Protocol (IP)

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

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

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

The Cisco Unified IP Phones support IPv6 address. For more information, see "Internet Protocol Version 6 (IPv6)" in the Cisco Unified Communications Manager Features and Services Guide.

Link Layer Discovery Protocol (LLDP)

(Cisco Unified IP Phone 6911 only)

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

The Cisco Unified IP Phone 6911 supports LLDP on the switch and 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/technologies/tk652/tk701/technologies_white_paper0900aecd804cd46d.html

Real-Time Transport Protocol (RTP)

RTP is a standard protocol for transporting 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.

Real-Time Control Protocol (RTCP)

RTCP works in conjunction with RTP to provide QoS data (such as jitter, latency, and round trip delay) on RTP streams.

By default, the phones have RTCP disabled, but you can enable it on each individual phone using Cisco Unified Communications Manager.

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 be used to establish, maintain, and terminate calls between two or more endpoints.

Like other VoIP protocols, SIP is designed to address 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).

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 Phone 6901 and 6911 use SCCP, version 20 for call control.

Transmission Control Protocol (TCP)

TCP is a connection-oriented transport protocol.

Cisco Unified IP Phones use TCP to connect to Cisco Unified Communications Manager.

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 when securely registering 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 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 specified by the DHCP server, you must manually assign the IP address of the TFTP server by using the Network Configuration menu on the phone.

For more information, go to 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 use UDP.

Cisco Unified IP Phone 6901 and 6911 Supported Features

Cisco Unified IP Phones function much like a digital business phone, allowing you to place and receive phone 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.

- 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, Call Forward, Transfer, Redial, Conference, and voice message system access. Cisco Unified IP Phones also provide a variety of other features. For more information on the features, see the Cisco Unified IP Phone 6901 and 6911 User Guide for Cisco Unified Communications Manager (SCCP and SIP).

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 information, such as an IP address, TFTP server, and subnet information.

Finally, because the Cisco Unified IP Phone is a network device, you can obtain detailed status information from the phone directly. This information can assist you with troubleshooting any problems users might encounter when using their IP Phones.

Cisco Unified IP Phones Security Features

Implementing 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 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 6901 and 6911 use the Phone security profile, which defines whether the device is nonsecure, authenticated, or encrypted. For information on applying 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, the phone configuration file contains 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 Cisco Unified Communications Manager Security Guide.

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

For more information about these features and about Cisco Unified Communications Manager and Cisco Unified IP Phone security, see the Cisco Unified Communications Manager Security Guide.

Note

Most security features are available only if the phone contains a certificate trust list (CTL). For more information about the CTL, see the "Configuring the Cisco CTL Client" chapter in Cisco Unified Communications Manager Security Guide.

Overview of Security Features

Feature

Description

Image authentication

Signed binary files (with the extension .zz.sgn) prevent tampering with the firmware image before it is loaded 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 Certificate Authority Proxy Function (CAPF).

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 by using TLS protocol. Cisco Unified Communications Manager will not register phones unless they can be authenticated by the Cisco Unified Communications Manager.

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 the file creation. Files that fail authentication are not written to flash memory on the phone. The phone rejects unauthenticated 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 a Cisco Unified Survivable Remote Site Telephony (SRST) reference for security and reset the dependent devices in Cisco Unified Communications Manager, the TFTP server adds the SRST certificate to the phone configuration file and sends the file to the phone. A secure phone uses a TLS connection to interact with the SRST-enabled router.

The configuration file uses one of the following extensions:

- .cnf.xml

- .cnf.xml.sgn

- .cnf.xml.enc.sgn

Media encryption

Uses SRTP to ensure that the media streams between supported phones proves secure and that only the intended phone receives and reads the data. Includes creating a media primary key pair for the phones, delivering the keys to the phones, and securing the delivery of the keys while the keys are in transport.

Signaling encryption

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

Certificate Authority Proxy Function (CAPF)

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 that displays a variety of operational statistics for the phone.

Phone hardening

The following is an additional security option that you control from Cisco Unified Communications Manager:

- Disabling access to web pages for a phone

802.1X Authentication

Defines the use of 802.1X authentication to request and gain access to the network.

Voice Quality Metrics

MOS LQK

Objective estimate of the Mean Opinion Score (MOS) for Listening Quality (LQK) that ranks audio quality from 5 (excellent) to 1 (bad). This score is based on audible-concealment events due to a frame loss in the preceding 8 seconds of the voice stream.

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 for the entire voice stream.

Min MOS LQK

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

Max MOS LQK

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

The following codecs provide the corresponding maximum MOS LQK scores under normal conditions with no frame loss:

- G.711: 4.5

- G.728/iLBC: 3.9

- G729A/AB: 3.7

MOS LQK Version

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

Authenticated, Encrypted, and Protected Phone Calls

Authenticated, Encrypted, and Protected Phone Calls

In an authenticated call, all devices participating in the establishment of the call are trusted devices, and authenticated by Cisco Unified Communications Manager.

In an encrypted call, all devices participating in the establishment of the call are trusted devices, and authenticated by Cisco Unified Communications Manager. In addition, call signaling and media streams are encrypted. An encrypted call offers a high level of security, providing integrity and privacy to the call.

If the call is routed through non-IP call legs, for example, PSTN, the call may be nonsecure even though it is encrypted within the IP network.

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 is connected to a non-protected phone, the security tone does not play.

Note

Connections between two phones support protected calling. Some features, such as conference calling and shared lines, are not available when protected calling is configured. Protected calls are not authenticated.

Cisco Unified IP Phones Security Features

Identify Protected Calls

A protected call establishes when your phone and the phone on the other end are set up 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 do not support protected calls.

A protected call establishes using this process:

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

2. A security tone plays if the call connects to another protected phone, indicating that both ends of the conversation are encrypted and protected. If the call connects to a non protected phone, then the secure tone does not play.

Note

Connections between two phones support protected calling. Some features, such as conference calling and shared 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 establish and changes the security indication for the conference or blocks the completion of the call to maintain integrity and security in the system.

The following table provides information about changes to call security levels when using Barge for Cisco Unified IP Phone 6911.

802.1X Authentication

The following sections describe the 802.1X support on the Cisco Unified IP Phones.

- Overview

- Required Network Components

- Best Practices-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 Practices-Requirements and Recommendations

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

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

Note

Only Cisco Unified IP Phone 6911 has a PC port.

- Enabled: If you are using a switch that supports multi-domain 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, refer to 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 both the phone and the PC.

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

- Enabled: If you are using a switch that supports multi-domain authentication, you can continue to use the Voice VLAN.

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

Cisco Unified IP Phone Deployment

When deploying 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 setting up and configuring a Cisco IP telephony network, see the "System Configuration Overview "chapter in Cisco Unified Communications Manager System Guide.

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

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 sending and receiving calls.

- Cisco Unified IP Phone and Cisco Unified Communications Manager Interactions

- Cisco Unified IP Phone 6911 and VLAN Interaction

- Cisco Unified IP Phone and Cisco Unified Communications Manager Express 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, 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

- Configuration file using 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 phones described in this chapter, see the "Cisco Unified IP Phone Configuration" chapter in the Cisco Communications Manager Administration 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, go to the following URL and install the latest support patch for your version of Cisco Unified Communications Manager:

http://tools.cisco.com/support/downloads/go/Redirect.x?mdfid=278875240

Cisco Unified IP Phone 6911 and VLAN Interaction

The Cisco Unified IP Phone 6911 has an internal Ethernet switch, enabling forwarding of packets to the phone, and to the access port and the network port on the back of the phone.

Note

The Cisco Unified IP Phone 6901 does not have a PC port.

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, additional IP addresses might not be available to assign the phone to the same subnet as other devices connected to the same port.

- Data traffic present on the VLAN supporting phones might reduce the quality of VoIP traffic.

- Network security may require isolation of the VLAN voice traffic from the VLAN data traffic.

You can resolve these issues by isolating the voice traffic onto a separate VLAN. The switch port that the phone connects to 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 connected to the switch through the access port of the IP Phone (native VLAN)

Isolating the phones on a separate, auxiliary VLAN increases the quality of the voice traffic and allows a large number of phones to be added to an existing network when there are not enough IP addresses for each phone.

Phone Configuration Files

The TFTP server stores the phone configuration files that define Cisco Unified Communications Manager connection parameters. In general, any time you make a change in Cisco Unified Communications Manager that requires the phone to be reset, a change is automatically made to the phone configuration file.

Configuration files also contain information about which image load the phone should be running. If this image load differs from the one currently loaded on a phone, the phone contacts the TFTP server to request the required load files.

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.

Note

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

If you configure security-related settings in Cisco Unified Communications Manager, the phone configuration file contains 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 Cisco Unified Communications Manager Security Guide. 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 from the TFTP server when the following conditions exist:

- You have enabled autoregistration in Cisco Unified Communications Manager

- The phone has not been added to the Cisco Unified Communications Manager database

- The phone is registering for the first time

If autoregistration is not enabled and the phone is not added to the Cisco Unified Communications Manager database, the system rejects the phone registration request.

If the phone registers and works in encrypted mode, the phone accesses the configuration file named SEPmac_address.cnf.xml.enc.sgn. If the SEPmac_address.cnf.xml.enc.sgn does not exist on the TFTP server, the phone requests the file SEPmac_address.cnf.xml.sgn. That is, if the phone works in encrypted mode with TFTP Encrypted Config selected, the phone accesses the configuration file named SEPMac_addr.cnf.xml.enc.sgn. If the phone works in encrypted mode with TFTP Encrypted Config not selected, the phone accesses the file SEPMac_addr.cnf.xml.sgn. To enable TFTP Encrypted Configuration, select the TFTP Encrypted Config check box in the Phone Security Profile Configuration page. You can access this page from the Cisco Unified Communications Manager by selecting System > Security > Phone Security Profile and clicking Add New.

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

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 on phone configuration settings, see the "Cisco Unified IP Phone Configuration" chapter in the Cisco Communications Manager Administration Guide.

Phone Startup Process

When connecting to the VoIP network, the Cisco Unified IP Phone 6901 and 6911 go through a standard startup process that is described in the following list. Depending on your specific network configuration, not all these steps may occur on your Cisco Unified IP Phone.

1. Obtain power from the switch. If a phone does not use external power, the switch provides in-line power through the Ethernet cable attached to the phone. For more information, see Cisco Unified Communications Manager Phone Addition Methods and Startup Problems.

2. Configure VLAN. If the Cisco Unified IP Phone connects to a Cisco Catalyst switch, the switch informs the phone of the voice VLAN defined on the switch. The phone needs to know the VLAN membership before proceeding with the Dynamic Host Configuration Protocol (DHCP) request for an IP address.

For more information, see Cisco Unified IP Phone Network Settings Setup and Startup Problems.

3. Obtain an IP address. If the Cisco Unified IP Phone uses DHCP to obtain an IP address, the phone queries the DHCP server to obtainthe address. If you are not using DHCP in your network, you must assign static IP addresses to each phone locally.

For more information, see Cisco Unified IP Phone Network Settings Setup and Startup Problems.

4. 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 assigned by DHCP.

For more information, see Cisco Unified IP Phone Network Settings Setup and Startup Problems.

5. Request the configuration file. The TFTP server stores configuration files that define parameters for connecting to Cisco Unified Communications Manager and other information for the phone.

For more information, see Cisco Unified Communications Manager Phone Addition Methods and Startup Problems.

6. Load the stored phone image. The Cisco Unified IP Phone has nonvolatile flash memory to store firmware images and user-defined preferences. At startup, the phone runs a bootstrap loader that loads a phone image stored in flash memory. Using this image, the phone initializes the software and hardware.

For more information, see Startup Problems.

7. 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 obtaining 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 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.

For more information, see Startup Problems

Cisco Unified Communications Manager Phone Addition Methods

Before installing the Cisco Unified IP Phone, you must choose a method for adding phones to the Cisco Unified Communications Manager database. Each phone type requires a fixed number of device license units and the available number of unit licenses on the server may impact phone registration. For more information on licensing, see the "Licenses for Phones" section in the Cisco Unified Communications Manager System Guide.

The following table provides an overview of the Cisco Unified Communications Manager phone addition methods.

Methods for Adding Phones to the Cisco Unified Communications Manager Database

Using BAT

Yes

Allows for simultaneous registration of multiple phones

- Autoregistration Phone Addition

- Autoregistration and TAPS Phone Addition

- Cisco Unified Communications Manager Phone Addition

- Add Phones Using BAT Phone Template

Autoregistration Phone Addition

By enabling 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 Communications Manager 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 you use autoregistration to add less than 100 phones to your network. To add more than 100 phones to your network, use the Bulk Administration Tool (BAT). See Add Phones Using BAT Phone Template.

The system disables autoregistration 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 the "Enabling 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 automatically disables. When you configure the cluster for nonsecure mode through the Cisco CTL client, autoregistration automatically enables.

Autoregistration and TAPS Phone Addition

You can add phones with autoregistration the Tool for Auto-Registered Phones Support (TAPS), 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 phone configuration files.

Note

Cisco recommends 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). See Add Phones Using BAT Phone Template.

To implement TAPS, you or the end user 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 Cisco Unified Communications Manager database contains the correct MAC address for the phone.

Autoregistration must be enabled in Cisco Unified Communications Manager (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 the "Bulk Administration" chapter in Cisco Unified Communications Manager Administration Guide.

Cisco Unified Communications Manager Phone Addition

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

For information about determining a MAC address, see Cisco Unified IP Phone MAC Address Determination.

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 Overview" chapter in the Cisco Unified Communications Manager System Guide.

Add Phones Using BAT Phone Template

The Cisco Unified Communications Manager Bulk Administration Tool (BAT) enables you to perform batch operations, including registration, on multiple phones. To access BAT, choose Bulk Administration in Cisco Unified Communications Manager Administration,

To add phones by using BAT only (not in conjunction with TAPS), you must obtain the appropriate MAC address for each phone.

For information about determining a MAC address, see Cisco Unified IP Phone MAC Address Determination.

For detailed instructions about adding phones using the Bulk Administration menu, see the Cisco Unified Communications Manager Bulk Administration Guide, chapter "Inserting Phones".

To add a phone to the Cisco Unified Communications Manager using the BAT phone template, perform these steps:

Step 5

Click Save.

Step 6

From Cisco Unified Communications Manager, choose Device > Phone > Add New to add a phone using an existing BAT phone template.

Cisco Unified IP Phones and Different Protocols

The Cisco Unified IP Phone can operate with SCCP (Skinny Client Control Protocol) or SIP (Session Initiation Protocol). You can convert a phone that is using one protocol to use the other protocol.

- Convert New Phone from SCCP to SIP

- In-Use Phone Protocol to Protocol Conversion

- Deploy Phone in SCCP and SIP Environment

Convert New Phone from SCCP to SIP

A new, unused phone uses SCCP. To convert this phone to SIP, perform these steps:

Procedure

Step 1

Take one of these actions:

- To autoregister the phone, set the Auto Registration Phone Protocol parameter in Cisco Unified Communications Manager to SIP.

- To provision the phone using the Bulk Administration Tool (BAT), choose the appropriate phone model and choose SIP from the BAT.

For more information, see Cisco Unified Communications Manager Bulk Administration Guide.

- To provision the phone manually, make the appropriate changes for SIP on the Phone configuration window in Cisco Unified Communications Manager.

For more information, see Cisco Unified Commiunications Manager Administration Guide.

Step 2

If you are not using DHCP in your network, configure the network parameters for the phone. See Network Settings.

Step 3

To save the configuration updates,

1. Click Apply Config.

2. When the Apply Configuration Information window displays, click OK.

3. Tell the user to power cycle the phone.

In-Use Phone Protocol to Protocol Conversion

Phones using SCCP can be upgraded to use SIP. To change from SCCP to SIP, the phone firmware must be updated to the recommended SIP version before the phones can register. New Cisco Unified IP Phones ship from the factory with SCCP phone firmware. These new phones must be upgraded to the recommended SIP version before they can complete registration.

For information about how to convert an in-use phone from one protocol to the other, see the Cisco Unified Communications Manager Administration Guide, chapter "Cisco Unified IP Phone Configuration", section "Migration Existing Phone Configuration to a Different Phone".

Deploy Phone in SCCP and SIP Environment

To deploy Cisco Unified IP Phones in an environment that includes SCCP and SIP and in which the Cisco Unified Communications Manager autoregistration parameter specifies SCCP, perform these general steps:

Procedure

Step 1

Set the Cisco Unified Communications Manager auto_registration_protocol parameter to SCCP.

Step 2

From Cisco Unified Communications Manager, choose System > Enterprise Parameters.

Step 3

Install the phones.

Step 4

Change the Auto Registration Protocol enterprise parameter to SIP.

Step 5

Autoregister the SIP phones.

Cisco Unified IP Phone MAC Address Determination

Several procedures described in this manual require you to determine the MAC address of a Cisco Unified IP Phone. You can determine the MAC address of a phone in these ways:

Telephony Features for the Cisco Unified IP Phones

Feature

Description

Configuration reference

Agent Greeting

Allows an agent to create and update a prerecorded greeting that plays at the beginning of a call, such as a customer call, before the agent begins the conversation with the caller. The agent can record greetings and update them, as required.

When a customer calls, both the agent and the customer can hear the prerecorded greeting. The agent can remain on mute until the greeting ends or answer the call over the greeting.

All codecs supported for the phone are supported for Agent Greeting calls.

To enable Agent Greeting in the Cisco Unified CM Administration application, choose Device > Phone, and locate the IP Phone that you want to configure. Scroll to the Device Information Layout pane and set the Built In Bridge field to On or Default.

If Built In Bridge is set to Default, choose System > Service Parameter and select the appropriate Server and Service. Scroll to the Clusterwide Parameters (Device - Phone) pane and set Builtin Bridge Enable to On.

For more information, see:

- Cisco Unified Communications Manager Features and Services Guide, "Barge and Privacy" chapter

- Cisco Unified Communications Manager System Guide, "Cisco Unified IP Phones" chapter

Audible Message Waiting Indicator (AMWI)

A stutter tone from the handset or speakerphone indicates that a user has one or more new voice messages on a line.

For more information, see the Cisco Unified Communications Manager System Guide, "Cisco Unified IP Phone" chapter.

Auto Answer

(Cisco Unified IP Phone 6911 only)

Connects incoming calls automatically after a ring or two.

Auto Answer works with the speakerphone.

For more information, see the Cisco Unified Communications Manager Administration Guide, "Directory Number Configuration" chapter.

Automatic Port Synchronization

(Cisco Unified IP Phone 6911 only)

When the Cisco Unified CM 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 to eliminate packet loss. When automatic port synchronization is enabled, Cisco recommends that both ports autonegotiate. If one port autonegotiates and the other uses a fixed speed, the phone synchronizes to the fixed port speed.

Note

If both the ports use fixed speed, the Automatic Port Synchronization feature is ineffective. 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 CM if the phone is powered by PoE.

To configure the parameter in the Cisco Unified CM 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 one of the following windows:

- Enterprise Phone Configuration (System > Enterprise Phone Configuration)

- Common Phone Profile Configuration (Device > Device Settings > Common Phone Profile)

EnergyWise Setup on Cisco Unified IP Phone 6901 and 6911

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 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 the 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.

The following table explains the Cisco Unified Communications Manager fields that control the EnergyWise settings. You configure these fields in Cisco Unified Communications Manager in the Product Specific configuration window, by choosing Device > Phone.

EnergyWise Configuration Fields

Field

Description

Enable Power Save Plus

Selects the schedule of days for which the phone powers down. 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 (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 fully 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 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 24:00.

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’s designated volume level. The audible alert schedule is:

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

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

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

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

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.

EnergyWise Secret

The security secret password that is used to communicate with the endpoints in the EnergyWise domain. The maximum length is 127.

Allow EnergyWise Overrides

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

- The settings in Cisco Unified CM Administration take effect on schedule even if EnergyWise sends an override.

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.), that directive will remain in effect (assuming no phone user intervention occurs) until the configured Phone On Time at 6:00 a.m.

- At 6:00 a.m., the phone turns on and resumes receiving the power level changes from the settings in Unified Communications Manager.

- 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.

Description

Possible Explanation and Action

CFG file not found

The name-based and default configuration file was not found on the TFTP Server.

The Cisco Unified Communications Manager creates the configuration file for the phone when the phone is added to the database. If the phone has not been added to the Cisco Unified Communications Manager database, the TFTP server generates a CFG File Not Found response.

Phone is not registered with Cisco Unified Communications Manager. You must manually add the phone to Cisco Unified Communications Manager if you are not allowing phones to autoregister. For more information, see the Cisco Unified Communications Manager Phone Addition Methods.

If you are using DHCP, verify that the DHCP server is pointing to the correct TFTP server.

If you are using static IP addresses, check the TFTP server configuration.

CFG TFTP Size Error

The configuration file is too large for the file system on the phone.

Power cycle the phone.

Checksum Error

Downloaded software file is corrupted.

Obtain a new copy of the phone firmware and place it in the TFTPPath directory. You should only copy files into this directory when the TFTP server software is shut down, otherwise the files may be corrupted.

DHCP timeout

DHCP server did not respond.

- Network is busy: The errors should resolve themselves when the network load reduces.

- No network connectivity between the DHCP server and the phone: Verify the network connections.

- DHCP server is down: Check the DHCP server configuration.

- Errors persist: Consider assigning a static IP address.

DNS timeout

DNS server did not respond.

- Network is busy: The errors should resolve themselves when the network load reduces.

- No network connectivity between the DNS server and the phone: Verify the network connections.

- DNS server is down: Check the DNS server configuration.

DNS unknown host

DNS could not resolve the name of the TFTP server or Cisco Unified Communications Manager.

- Verify that the host names of the TFTP server or Cisco Unified Communications Manager are configured properly in DNS.

- Consider using IP addresses rather than host names.

Duplicate IP

Another device is using the IP address assigned to the phone.

- If the phone has a static IP address, verify that you have not assigned a duplicate IP address.

- If you are using DHCP, check the DHCP server configuration.

Error update locale

One or more localization files could not be found in the TFTPPath directory or were not valid. The locale was not changed.

From Cisco Unified Operating System Administration, check that the following files are located within subdirectories in the TFTP File Management:

- Located in subdirectory with the same name as network locale:

- tones.xml

- Located in subdirectory with the same name as user locale:

- glyphs.xml

- dictionary.xml

- kate.xml

- Additional Troubleshooting Information

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 the Phone Startup Verification.

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 Flashing Red Light

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 as described in Phone Startup Verification.

Cause

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

Solution

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

- 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 that 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.

- Verify that the phone is receiving power:

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

- 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.

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

If after attempting these solutions, the phone still does not function, contact a Cisco technical support representative for additional assistance.

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

Use this section if the phone proceeds past the first stage of the startup process (all LED buttons on) but 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.

In addition, problems with security may prevent the phone from starting up properly. For more information, see General Troubleshooting Information.

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. For instructions about accessing status messages and suggested actions to resolve the errors, see the Device Logs Area.

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.

On the Cisco Unified IP Phone, press the *, #, and 0 buttons simultaneously, enter the password, and then follow the voice prompts to review the 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 the Cisco Unified IP Phone Network Settings Setup for instructions.

- If you are using DHCP, check the IP addresses distributed by your DHCP server. Refer to the Understanding and Troubleshooting DHCP in Catalyst Switch or Enterprise Networks document, available at this URL:

http://www.cisco.com/en/US/tech/tk648/tk361/technologies_tech_note09186a00800f0804.shtml

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 Configuration File.

Cisco Unified Communications Manager Phone Registration

Problem

The phone is not registered with the 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) there is a sufficient number of unit licenses. 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 the Cisco Unified IP Phones and Different Protocols.

If the phone is already in the Cisco Unified Communications Manager database, the phone configuration file may be damaged. For assistance, see Create New Configuration File.

For more information about licensing, see the "Licences for phones" section of the Cisco Unified Communications Manager System Guide.

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 Flashing Red Light

Problem

The phone fails to boot, and the message indicator flashes a red light.

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 phone displays a flashing red light.

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 Perform 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.

- Physical Connection Problems

- Intermittent Network Outages

- DHCP Settings Errors

- Static IP Address Settings 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 Settings Errors

Problem

The DHCP settings may be incorrect.

Solution

Verify that you have properly configured the phone to use DHCP. For more information see, Cisco Unified IP Phone Network Settings Setup. Verify that the DHCP server is set up properly. Verify the DHCP lease duration. Cisco recommends that you set the lease duration to 8 days.

Static IP Address Settings 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. For more information, see Cisco Unified IP Phone Network Settings Setup.

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 the same switch as the 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. For more information, see Cisco Unified IP Phone 6911 and VLAN Interaction.

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 if a Cisco Unified IP Phone received a command from Cisco Unified Communications Manager to reset by pressing Applications on the phone and choosing Administrator Settings > Status > Network Statistics.

- If the Restart Cause field displays Reset-Reset, the phone received a Reset/Reset from Cisco Unified Communications Manager Administration.

- If the Restart Cause field displays Reset-Restart, the phone reset because it received a Reset/Restart 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.

Audio Problems

The following sections describe how to resolve audio problems.

- Poor Audio Quality with Calls That Route Outside Cisco Unified Communications Manager

- Choppy Speech

- No Speech Path

Poor Audio Quality with Calls That Route Outside Cisco Unified Communications Manager

Problem

Poor quality occurs with tandem audio encoding. Tandem encoding can occur when calls are made between an IP Phone and a digital cellular phone, when a conference bridge is used, or in situations where IP-to-IP calls are partially routed across the PSTN.

Cause

In these cases, use of voice codecs such as G.729 and iLBC may result in poor voice quality.

Solution

Use the G.729 and iLBC codecs only when absolutely necessary.

Choppy Speech

Problem

A user complains of choppy speech on a call.

Cause

There may be a mismatch in the jitter configuration.

Solution

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.

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

The following sections help troubleshoot general telephone call problems.

- Phone Call Cannot Be Established

- Phone Does Not Recognize DTMF Digits or Digits Are Delayed

Phone Call Cannot Be Established

Problem

A user complains about not being able to make a call.

Cause

The phone does not have a DHCP IP address, is unable to register to Cisco Unified Communications Manager. Phones with an LCD display show the message Configuring IP or Registering. Phones without an LCD display play the reorder tone (instead of dial tone) in the handset when the user attempts to make a call.

Solution

1. 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.

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

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.

- Check TFTP Settings

- Create New Configuration File

- Determine DNS or Connectivity Issues

- Start Service

Check TFTP Settings

Procedure

Step 1

Determine the IP address of the TFTP server used by the phone by pressing the *, #, and 0 buttons simultaneously, entering the password, and then following the voice prompts to review the network setting.

Step 2

If you have assigned a static IP address to the phone, check the setting for the TFTP Server 1 option. See the Cisco Unified IP Phone Network Settings Setup.

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 or Option 66.

Step 4

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 the Cisco Unified IP Phone Network Settings Setup for instructions.

Create New 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 Cisco Unified Communications Manager deletes the configuration file from the TFTP server. The assigned directory numbers for the phone remain in the Cisco Unified Communications Manager database. They are called unassigned DNs and can be assigned to 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. Refer toFor more information, see Cisco Unified Communications Manager Administration Guide.

- 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 there is no button on the phone for the line, meaning that no calls to the number 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 the Cisco Unified Communications Manager Phone Addition Methods for details.

Step 4

Power cycle the phone.

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 Reset Settings menu to reset phone settings to their default values. For more information, see Cisco Unified IP Phone Reset or Restore.

Step 2

Modify DHCP and IP settings:

1. Disable DHCP. For instructions, see Cisco Unified IP Phone Network Settings Setup.

2. Assign static IP values to the phone. For instructions, see Cisco Unified IP Phone Network Settings Setup. Use the same default router setting used for other functioning Cisco Unified IP Phones.

3. Assign a TFTP server. For instructions, see Cisco Unified IP Phone Network Settings Setup. 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 the DNS name.

Step 5

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

Step 6

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.

General Troubleshooting Information

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

Cisco Unified IP Phone Troubleshooting

Summary

Explanation

Connecting a Cisco Unified IP Phone to another Cisco Unified IP Phone through the PC port.

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 will not work.

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 regain connectivity until a broadcast storm ends.

Moving a network connection from the phone to a workstation.

If you power your phone through the network connection, you must be careful if you decide to unplug the network connection of the phone 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 there is no longer a phone 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 the Access Phone Configuration Settings for details.

Phone resetting.

The phone resets when it loses contact with the Cisco Unified Communications Manager software. This lost connection can be due to any network connectivity disruption, including cable breaks, switch outages, and switch reboots.

Codec mismatch between the phone and another device.

The RxType and the TxType statistics show the codec that is being 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 match, verify that the other device can handle the codec conversation or that a transcoder is in place to handle the service.

Sound sample mismatch between the phone and another device.

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

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, reenable the port from the switch.

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

- 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 using the image in the inactive partition of flash memory to boot up).

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.

To perform a factory reset of a phone, you can use the IVR to reset the network settings to factory default or you can perform the following steps:

Procedure

Step 1

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

The phone begins its power-up cycle.

Step 2

While the phone is powering up, press and hold # button until the Line LED turns green.

Step 3

Release the # button and press 123456789*0#.

The line button LED turns red. The phone reboots when it is finished.

Voice Quality Monitoring

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

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

- Concealed Second metrics: Shows 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.

- Mean Opinion Score (MOS) for Listening Quality (LQK) Voice Metrics: Uses a numeric score to estimate the relative voice-listening quality. The Cisco Unified IP Phones calculate the MOS LQK based audible-concealment events due to a frame loss in the preceding 8 seconds and includes weighting factors such as codec type and frame size.

MOS LQK scores are produced by a Cisco-proprietary algorithm, the Cisco Voice Transmission Quality (CVTQ) index. Depending on the MOS LQK version number, these scores may comply 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. A Conceal Ratio of zero indicates that the IP network is delivering frames and packets on time with no loss.

You can access voice quality metrics remotely by using Streaming Statistics (see Remote Monitoring).

Voice Quality Metrics

When using 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 also important to distinguish significant changes from random changes in metrics. Significant changes are scores that change about 0.2 MOS or more and persist in calls that last longer than 30 seconds. Conceal ratio changes indicate a frame loss greater than 3 percent.

The MOS LQK scores can vary based on the codec that the Cisco Unified IP Phone uses. The following codecs provide these corresponding maximum MOS LQK scores under normal conditions with zero frame loss for Cisco Unified Phones 6901 and 6911:

- G.711: 4.5 MOS LQK

- G.722: 4.5 MOS LQK

- G.728/iLBC: 3.9 MOS LQK

- G729A/AB: 3.7 MOS LQK

Cisco Voice Transmission Quality (CVTQ) does not support wideband (7 kHz) speech codecs, because ITU has not defined the extension of the technique to wideband. Therefore, MOS LQK 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 or a low packet loss, and lower scores (approximately 3.5) indicate low quality or a 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

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

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.

MOS LQK scores decrease significantly

Network impairment from packet loss or high jitter levels:

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

- Individual MOS LQK decreases may indicate bursty impairment.

Cross-check the conceal ratio and conceal seconds for evidence of packet loss and jitter.

MOS LQK scores increase significantly

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

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

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 only a dry soft cloth to gently wipe the phone. Do not apply liquids or powders directly on the phone. As with all non-weatherproof electronics, liquids and powders can damage the components and cause failures.

Phone Administration Overview

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

- Add a new user to Cisco Unified Communications Manager

- 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 the 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. Sample user and phone information used throughout these procedures includes:

- User’s Name: John Doe

- User ID: johndoe

- Phone model: 6901

- Protocol: SCCP

- 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

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 phone user by following these steps:

Procedure

Step 1

Step 2

Choose System > LDAP > LDAP Directory.

Step 3

Use the Find button to locate your LDAP directory.

Step 4

Click the LDAP directory name.

Step 5

Click Perform Full Sync Now.

Note

If you do not need to immediately synchronize the LDAP Directory to the 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 by following these steps:

Procedure

Step 1

Choose User Management > End User.

Step 2

Click Add New.

The End User Configuration window appears.

Step 3

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 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. Users can have multiple lines on their phones.

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

Step 4

Click Save.

Step 5

Proceed to the section Phone Setup.

Phone Setup

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

Procedure

Step 1

The configuration is based on the example of user johndoe.

1. In the Device Information pane of this window:

MAC Address

Enter the MAC address of the phone, listed on a sticker on the back of phone.

The MAC address is 12 hexadecimal characters long.

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

Description

This is an optional field where you can enter a useful description. This will help you if you need to search for information about this user.

Device Pool

Choose the device pool for which you want to assign this phone. The device pool defines sets of common characteristics for devices, such as region, date/time group, 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 features on a phone and identifies the predetermined number to be dialed after pressing the feature button. To configure the Predetermined Number for a feature, navigate to the Phone Button Template of Cisco Unified IP Phone 6911. In the template, 1 is always assigned to the line, so the button number minus 1 is the predetermined number that is provided by your system administrator.

Note

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

Common Phone Profile

From the drop-down list, choose a common phone profile from the list of available common phone profiles.

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

Calling Search Space

From the drop-down list, 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 (Calling routing > Class of Control > Calling Search Space). You can use the search fields and 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 list, 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.
