Before You Begin

Prerequisites for Configuring Cisco Unified CME

  • Base Cisco Unified CME feature license and phone user licenses that entitle you to use Cisco Unified CME are purchased.


Note
To support H.323 call transfers and forwards to network devices that do not support the H.450 standard, such as Cisco Unified Communications Manager, a tandem gateway is required in the network. The tandem gateway must be running Cisco IOS release 12.3(7)T or a later release and requires the Integrated Voice and Video Services feature license (FL-GK-NEW-xxx), which includes H.323 gatekeeper, IP-to-IP gateway, and H.450 tandem functionality.

  • Your IP network is operational and you can access Cisco web.

  • You have a valid Cisco.com account.

  • You have access to a TFTP server for downloading files.

  • Cisco router with all recommended services hardware for Cisco Unified CME is installed. For installation information, see Install Cisco Voice Services Hardware.

  • Recommended Cisco IOS IP Voice or higher image is downloaded to flash memory in the router.

  • VoIP networking must be operational. For quality and security purposes, we recommend separate virtual LANs (VLANs) for data and voice. The IP network assigned to each VLAN should be large enough to support addresses for all nodes on that VLAN. Cisco Unified CME phones receive their IP addresses from the voice network, whereas all other nodes such as PCs, servers, and printers receive their IP addresses from the data network. For configuration information, see Configure VLANs on a Cisco Switch.

Restrictions for Configuring Cisco Unified CME

  • Cisco Unified CME cannot register as a member of a Cisco Unified Communications Manager cluster.

  • For conferencing and music on hold (MOH) support with G.729, hardware digital signal processors (DSPs) are required for transcoding G.729 between G.711.

  • After a three-way conference is established, a participant cannot use call transfer to join the remaining conference participants to a different number.

  • Cisco Unified CME does not support the following:

    • CiscoWorks IP Telephony Environment Monitor (ITEM)

    • Element Management System (EMS) integration

    • Media Gateway Control Protocol (MGCP) on-net calls

    • Java Telephony Application Programming Interface (JTAPI) applications, such as the Cisco IP Softphone, Cisco Unified Communications Manager Auto Attendant, or Cisco Personal Assistant

    • Telephony Application Programming Interface (TAPI)

      Cisco Unified CME implements only a small subset of TAPI functionality. It supports operation of multiple independent clients (for example, one client per phone line), but not full support for multiple-user or multiple-call handling, which is required for complex features such as automatic call distribution (ACD) and Cisco Unified Contact Center (formerly Cisco IPCC). Also, this TAPI version does not have direct media- and voice-handling capabilities.

Information About Planning Your Configuration

System Design

Traditional telephony systems are based on physical connections and are therefore limited in the types of phone services that they can offer. Because phone configurations and directory numbers in a Cisco Unified CME system are software entities and because the audio stream is packet-based, an almost limitless number of combinations of phone numbers, lines, and phones can be planned and implemented.

Cisco Unified CME systems can be designed in many ways. The key is to determine the total number of simultaneous calls you want to handle at your site and at each phone at your site, and how many different directory numbers and phones you want to have. Even a Cisco Unified CME system has its limits, however. Consider the following factors in your system design:

  • Maximum number of phones—This number corresponds to the maximum number of devices that can be attached. The maximum is platform- and version-dependent. To find the maximum for your platform and version, see Cisco CME Supported Firmware, Platforms, Memory, and Voice Products.

  • Maximum number of directory numbers—This number corresponds to the maximum number of simultaneous call connections that can occur. The maximum is platform- and version-dependent. To find the maximum for your platform and version, see Cisco CME Supported Firmware, Platforms, Memory, and Voice Products.

  • Telephone number scheme—Your numbering plan may restrict the range of telephone numbers or extension numbers that you can use. For example, if you have DID, the PSTN may assign you a certain series of numbers.

  • Maximum number of buttons per phone—You may be limited by the number of buttons and phones that your site can use. For example, you may have two people with six-button phones to answer 20 different telephone numbers.

The flexibility of a Cisco Unified CME system is due largely to the different types of directory numbers (DNs) that you can assign to phones in your system. By understanding types of DNs and considering how they can be combined, you can create the complete call coverage that your business requires. For more information about DNs, see Configuring Phones to Make Basic Calls.

After setting up the DNs and phones that you need, you can add optional Cisco Unified CME features to create a telephony environment that enhances your business objectives. Cisco Unified CME systems are able to integrate with the PSTN and with your business requirements to allow you to continue using your existing number plans, dialing schemes, and call coverage patterns.

When creating number plans, dialing schemes, and call coverage patterns in Cisco Unified CME, there are several factors that you must consider:

  • Is there an existing PBX or Key System that you are replacing and want to emulate?

  • Number of phones and phone users to be supported?

  • Do you want to use single-line or dual-line DNs?

  • What protocols does your voice network support?

  • Which call transfer and forwarding methods must be supported?

  • What existing or preferred billing method do you want to use for transferred and forwarded calls?

  • Do you need to optimize network bandwidth or minimize voice delay?

Because these factors can limit your choices for some of the configuration decisions that you will make when you create of a dialing plan, see the Cisco Unified Communications Manager Express Solution Reference Network Design Guide to help you understand the effect these factors have on your Cisco Unified CME implementation.

Toll Fraud Prevention

When a Cisco router platform is installed with a voice-capable Cisco IOS software image, appropriate features must be enabled on the platform to prevent potential toll fraud exploitation by unauthorized users. Deploy these features on all Cisco router Unified Communications applications that process voice calls, such as Cisco Unified Communications Manager Express (Cisco Unified CME), Cisco Survivable Remote Site Telephony (Cisco Unified SRST), Cisco Unified Border Element, Cisco IOS-based router and standalone analog and digital PBX and public-switched telephone network (PSTN) gateways, and Cisco contact-center VoiceXML gateways. These features include, but are not limited to, the following:

  • Disable secondary dial tone on voice ports—By default, secondary dial tone is presented on voice ports on Cisco router gateways. Use private line automatic ringdown (PLAR) for foreign exchange office (FXO) ports and direct-inward-dial (DID) for T1/E1 ports to prevent secondary dial tone from being presented to inbound callers.

  • Cisco router access control lists (ACLs)—Define ACLs to allow only explicitly valid sources of calls to the router or gateway, and therefore to prevent unauthorized Session Initiation Protocol (SIP) or H.323 calls from unknown parties to be processed and connected by the router or gateway.

  • Close unused SIP and H.323 ports—If either the SIP or H.323 protocol is not used in your deployment, close the associated protocol ports. If a Cisco voice gateway has dial peers configured to route calls outbound to the PSTN using either time division multiplex (TDM) trunks or IP, close the unused H.323 or SIP ports so that calls from unauthorized endpoints cannot connect calls. If the protocols are used and the ports must remain open, use ACLs to limit access to legitimate sources.

  • Change SIP port 5060—If SIP is actively used, consider changing the port to something other than well-known port 5060.

  • SIP registration—If SIP registration is available on SIP trunks, turn on this feature because it provides an extra level of authentication and validation that only legitimate sources can connect calls. If it is not available, ensure that the appropriate ACLs are in place.

  • SIP Digest Authentication—If the SIP Digest Authentication feature is available for either registrations or invites, turn this feature on because it provides an extra level of authentication and validation that only legitimate sources can connect calls.

  • Explicit incoming and outgoing dial peers—Use explicit dial peers to control the types and parameters of calls allowed by the router, especially in IP-to-IP connections used on Cisco Unified CME, Cisco Unified SRST, and Cisco Unified Border Element. Incoming dial peers offer additional control on the sources of calls, and outgoing dial peers on the destinations. Incoming dial peers are always used for calls. If a dial peer is not explicitly defined, the implicit dial peer 0 is used to allow all calls.

  • Explicit destination patterns—Use dial peers with more granularity than .T for destination patterns to block disallowed off-net call destinations. Use class of restriction (COR) on dial peers with specific destination patterns to allow even more granular control of calls to different destinations on the PSTN.

  • Translation rules—Use translation rules to manipulate dialed digits before calls connect to the PSTN to provide better control over who may dial PSTN destinations. Legitimate users dial an access code and an augmented number for PSTN for certain PSTN (for example, international) locations.

  • Tcl and VoiceXML scripts—Attach a Tcl/VoiceXML script to dial peers to do database lookups or additional off-router authorization checks to allow or deny call flows based on origination or destination numbers. Tcl/VoiceXML scripts can also be used to add a prefix to inbound DID calls. If the prefix plus DID matches internal extensions, then the call is completed. Otherwise, a prompt can be played to the caller that an invalid number has been dialed.

  • Host name validation—Use the “permit hostname” feature to validate initial SIP Invites that contain a fully qualified domain name (FQDN) host name in the Request Uniform Resource identifier (Request URI) against a configured list of legitimate source hostnames.

  • Dynamic Domain Name Service (DNS)—If you are using DNS as the “session target” on dial peers, the actual IP address destination of call connections can vary from one call to the next. Use voice source groups and ACLs to restrict the valid address ranges expected in DNS responses (which are used subsequently for call setup destinations).

Install Cisco Voice Services Hardware


Note
Cisco routers are normally shipped with Cisco voice services hardware and other optional equipment that you ordered already installed. In the event that the hardware is not installed or you are upgrading your existing Cisco router to support Cisco Unified CME or Cisco Unity Express, you will be required to install hardware components.

Voice bundles do not include all the necessary components for Cisco Unity Express. Contact the Cisco IP Communications Express partner in your area for more information about including Cisco Unity Express in your configuration.

Before you begin

  • Cisco router and all recommended hardware for Cisco Unified CME, and if required, Cisco Unity Express, is ordered and delivered, or is already onsite.

Procedure

Step 1

Install the Cisco router on your network. To find installation instructions for the Cisco router, access documents located at www.cisco.com>Technical Support & Documentation>Product Support>Routers>router you are using>Install and Upgrade Guides.

Step 2

Install Cisco voice services hardware.

  1. To find installation instructions for any Cisco interface card, access documents located at www.cisco.com>Technical Support & Documentation>Product Support>Cisco Interfaces and Modules>interface you are using>Install and Upgrade Guides or Documentation Roadmap.

  2. To install and configure your Catalyst switch, see Cisco Network Assistant.

  3. To find installation instructions for any Cisco EtherSwitch module, access documents located at www.cisco.com>Technical Support & Documentation>Product Support>Cisco Switches>switch you are using>Install and Upgrade Guides.

Step 3

Connect to the Cisco router using a terminal or PC with terminal emulation. Attach a terminal or PC running terminal emulation to the console port of the router.

Use the following terminal settings:

  • 9600 baud rate

  • No parity

  • 8 data bits

  • 1 stop bit

  • No flow control

Note

 
Memory recommendations and maximum numbers of Cisco IP phones identified in the next step are for common Cisco Unified CME configurations only. Systems with large numbers of phones and complex configurations may not work on all platforms and can require additional memory or a higher performance platform.

Step 4

Log in to the router and use the show version EXEC command or the show flash privileged EXEC command to check the amount of memory installed in the router. Look for the following lines after issuing the show version command.

Example:


Router> show version ...
Cisco 2691 (R7000) processor (revision 0.1) with 177152K/19456K bytes of memory
...
31360K bytes of ATA System Compactflash (Read/Write)

The first line indicates how much Dynamic RAM (DRAM) and Packet memory is installed in your router. Some platforms use a fraction of their DRAM as Packet memory. The memory requirements take this into account, so you have to add both numbers to find the amount of DRAM available on your router (from a memory requirement point of view).

The second line identifies the amount of flash memory installed in your router.

or

Look for the following line after issuing the show flash command. Add the number available to the number used to determine the total flash memory installed in the Cisco router. 


Router# show flash 
...
2252800 bytes available, (29679616 bytes used]

Step 5

Identify DRAM and flash memory requirements for the Cisco Unified CME version and Cisco router model you are using. To find Cisco Unified CME specifications, see the appropriate Cisco Unified CME Supported Firmware, Platforms, Memory, and Voice Products.

Step 6

Compare the amount of memory required to the amount of memory installed in the router. To install or upgrade the system memory in the router, access documents located at www.cisco.com>Technical Support & Documentation>Product Support>Routers>router you are using>Install and Upgrade Guides.

Step 7

Use the memory-size iomem i/o memory-percentage privileged EXEC command to disable Smartinit and allocate ten percent of the total memory to Input/Output (I/O) memory.

Example:


Router# memory-size iomem 10

Install Cisco IOS Software


Note
The Cisco router in a voice bundle is preloaded with the recommended Cisco IOS software release and feature set plus the necessary Cisco Unified CME phone firmware files to support Cisco Unified CME and Cisco Unity Express. If the recommended software is not installed or if you are upgrading an existing Cisco router to support Cisco Unified CME and Cisco Unity Express, you will be required to download and extract the required image and files.

To verify that the recommended software is installed on the Cisco router and if required, download and install a Cisco IOS Voice or higher image, perform the following steps.

Before you begin

  • The Cisco router is installed including sufficient memory, all Cisco voice services hardware, and other optional hardware.

Procedure

Step 1

Identify which Cisco IOS software release is installed on router. Log in to the router and use the show version EXEC command. 


Router> show version 
Cisco Internetwork Operating System Software 
IOS (tm) 12.3 T Software (C2600-I-MZ), Version 12.3(11)T, RELEASE SOFTWARE

Step 2

Compare the Cisco IOS release installed on the Cisco router to the information in the Cisco Unified CME and Cisco IOS Software Version Compatibility Matrix to determine whether the Cisco IOS release supports the recommended Cisco Unified CME.

Step 3

If required, download and extract the recommended Cisco IOS IP Voice or higher image to flash memory in the router.

To find software installation information, access information located at www.cisco.com>Technical Support & Documentation>Product Support> Cisco IOS Software>Cisco IOS Software Mainline release you are using> Configuration Guides> Cisco IOS Configuration Fundamentals and Network Management Configuration Guide>Part 2: File Management>Locating and Maintaining System Images.

Step 4

To reload the Cisco Unified CME router with the new software after replacing or upgrading the Cisco IOS release, use the reload privileged EXEC command.

Example: 

Router# reload 
System configuration has been modified. Save [yes/no]:
Y 
Building configuration...
OK
Proceed with reload? Confirm.
11w2d: %Sys-5-RELOAD: Reload requested by console. Reload reason: reload command . System bootstrap, System Version 12.2(8r)T, RELEASE SOFTWARE (fc1)
