The G.729a codec is not supported.

Task List to Create the Integration Through a SIP Trunk

Before doing the following tasks to integrate Cisco Unity with Cisco Unified CM Express through a SIP trunk, confirm that the Cisco Unity server is ready for the integration by completing the applicable tasks in the applicable Cisco Unity installation guide. If you are installing a new Cisco Unity server by using the applicable Cisco Unity installation guide, you may have already completed some of the following tasks.

1. Review the system and equipment requirements to confirm that all phone system and Cisco Unity server requirements have been met. See the "Requirements" section.

2. Plan how the voice messaging ports will be used by Cisco Unity. See Chapter 2, "Planning How the Voice Messaging Ports Will Be Used by Cisco Unity."

3. Program Cisco Unified CM Express. See the "Programming the Cisco Unified Communications Manager Express Phone System for Integrating with Cisco Unity" section.

4. Create the integration. See the "Creating a New Integration with Cisco Unified Communications Manager Express" section.

5. If want to disable transcoding into the G.729a audio format, remove the G.729a codec from the Cisco Unity server. See Chapter 4, "Disabling Transcoding into the G.729a Audio Format."

6. Test the integration. See Chapter 5, "Testing the Integration."

Requirements

The Cisco Unified Communications Manager Express SIP trunk integration supports configurations of the following components:

Phone System

•Cisco Unified CM Express.

For details on compatible versions of Cisco Unified CM Express, refer to the SIP Trunk Compatibility Matrix: Cisco Unity, Cisco Unified CM, and Cisco Unified CM Express at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_device_support_tables_list.html.

•A compatible Cisco IOS software version. Refer to the Cisco Unified Communications Manager Express and Cisco IOS Software Version Compatibility Matrix at http://www.cisco.com/en/US/products/sw/voicesw/ps4625/prod_installation_guides_list.html.

•Cisco Unified CM Express feature license.

•Cisco IP phone feature licenses, and Cisco licenses for other H.323-compliant devices or software (such as Cisco VirtualPhone and Microsoft NetMeeting clients) that will be connected to the network, as well as one license for each Cisco Unity port.

•For the Cisco Unified CM Express extensions, SIP phones that support DTMF relay as described in RFC-2833. For a list of supported Cisco IP phone models, refer to the applicable Cisco Unified Communications Manager Express Supported Firmware, Platforms, Memory, and Voice Products at http://www.cisco.com/en/US/products/sw/voicesw/ps4625/prod_installation_guides_list.html.

•For the Cisco Unified CM Express extensions, one of the following configurations:

–(Best practice) Only SIP phones that support DTMF relay as described in RFC-2833.

–Both SCCP phones and SIP phones.

Note that older SCCP phone models may require a Media Termination Point (MTP) to function correctly.

•A LAN connection in each location where you will plug an IP phone into the network.

Cisco Unity Server

•The applicable version of Cisco Unity. For details on compatible versions of Cisco Unity, refer to the SIP Trunk Compatibility Matrix: Cisco Unity, Cisco Unified CM, and Cisco Unified CM Express at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_device_support_tables_list.html.

•Cisco Unity installed and ready for the integration, as described in the applicable Cisco Unity installation guide at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_installation_guides_list.html.

•A license that enables the appropriate number of voice messaging ports.

Centralized Voice Messaging

Cisco Unity supports centralized voice messaging by supporting various inter-phone system networking protocols including, for example, proprietary protocols such as Avaya DCS, Nortel MCDN, or Siemens CorNet, and standards-based protocols such as QSIG or DPNSS. For details, see the "Centralized Voice Messaging" section in the "Integrating Cisco Unity with the Phone System" chapter of the Design Guide for Cisco Unity Release 5.x at http://www.cisco.com/en/US/docs/voice_ip_comm/unity/5x/design/guide/5xcudgx.html.

Programming the Cisco Unified Communications Manager Express Phone System for Integrating with Cisco Unity

For details on programming the Cisco Unified CM Express router for the integration with Cisco Unity, refer to the "Integrating Voice Mail" chapter of the Cisco Unified Communications Manager Express System Administrator Guide at http://www.cisco.com/en/US/products/sw/voicesw/ps4625/products_installation_and_configuration_guides_list.html.

Creating a New Integration with Cisco Unified Communications Manager Express

After ensuring that Cisco Unified Communications Manager Express and Cisco Unity are ready for the integration, do the following procedures to set up the integration and to enter the port settings.

To Create an Integration

Step 1 If UTIM is not already open, on the Windows Start menu of the Cisco Unity server, click Programs > Cisco Unity > Manage Integrations. UTIM appears.

Step 2 In the left pane of the UTIM window, click Cisco Unity Server.

Step 3 On the Integration menu of the UTIM window, click New. The Telephony Integration Setup Wizard appears.

Step 4 On the Welcome page, click SIP (including CUCM/CCM) and click Next.

Step 5 On the Name This SIP Integration and Cluster page, enter the following settings, then click Next.

Step 10 If other integrations already exist, the Enter Trunk Access Code page appears. Enter the extra digits that Cisco Unity must use to transfer calls through the gateway to extensions on the other phone systems with which it is integrated. Then click Next.

Step 11 On the Reassign Subscribers page, any subscribers whose phone system integration has been deleted and who are not currently assigned to a phone system integration will appear in the list.

If no subscribers appear in the list, click Next and continue to Step 12.

Otherwise, select the subscribers that you want to assign to this phone system integration and click Next. You can use the following selection controls for selecting subscribers.

Step 14 At the prompt to restart the Cisco Unity services, click Yes. The Cisco Unity services restart.

Alternatively, you can restart the Cisco Unity services in UTIM on the Tools menu by clicking Restart Cisco Unity.

To Enter the Voice Messaging Port Settings for the Integration

Step 1 After the Cisco Unity services restart, on the View menu, click Refresh.

Step 2 In the left pane of the UTIM window, expand the phone system integration that you are creating.

Step 3 In the left pane, click the name of the cluster.

Step 4 In the right pane, on the Servers tab, confirm that the CUCM/CCM Security Mode field is set to Non-Secure.

Step 5 Click the Ports tab.

Step 6 Enter the settings shown in Table 3-7 for the voice messaging ports.

To get the best performance, use the first voice messaging ports for incoming calls and the last ports to dial out. This arrangement helps minimize the possibility of a collision, in which an incoming call arrives on a port at the same time that Cisco Unity takes the port off-hook to dial out.
