Cisco Unified Communications Manager supports several types of Cisco Unified Communications gateways. The Voice Gateways are used for call termination when the internal IP Telephony infrastructure has to communicate with the PSTN and other non-IP telecommunications devices, such as private branch exchanges (PBXs), key systems, analog phones, fax machines, and modems.<\/span><\/p>\n

 <\/p>\n

Trunk interfaces specify how the gateway communicates with the PSTN or other external devices by using time-division-multiplexing (TDM) signaling. Cisco Unified Communications Manager and Cisco gateways use a variety of TDM interfaces, however the supported TDM interfaces may vary based on the gateway generation. In general the Cisco Unified Communications Manager supports two major types of gateways based on the protocol being used to control them \u2013 Media Gateway Control Protocol (MGCP) and H.323 gateways. However, in the recent time there are more and more implementations of SIP trunks between the CUCM and the Voice gateway, sometimes referred as Cisco Unified Border Element (CUBE).<\/p>\n

Task 1: Add a H.323 Gateway to Cisco Unified Communications Manager<\/h2>\n

In this task we will add both routers as an H.323 gateways to Cisco Unified Communications Manager.<\/p>\n

Activity Procedure<\/h3>\n

Complete these steps:<\/p>\n

    \n
  1. On Cisco Unified Communications Manager Administration page, from the menu select Device > Gateway<\/strong> and click Add New<\/strong>.<\/li>\n
  2. For gateway type, select H.323 Gateway<\/strong>, and click Next<\/strong>.<\/li>\n
  3. On the Gateway Configuration page, use the following parameters:
    \n– Device Name: 10.1.1.101 (the IP address of the H323 Gateway connected to the Voice LAN)
    \n– Device Pool: SanJose
    \n– Uncheck\u00a0
  4. Click Save<\/strong>.<\/li>\n
  5. Click Reset<\/strong> button, and another Reset<\/strong> button.<\/li>\n
  6. Now the IP address of the H323 gateway will appear.<\/li>\n
  7. Repeat steps 1 – 5 for the second router with the following parameters:
    \n– Device Name: 10.1.1.102 (the IP address of the H323 Gateway connected to the Voice LAN)
    \n– Device Pool: Chicago
    \n– Uncheck\u00a0
