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 In this task we will add both routers as an H.323 gateways to Cisco Unified Communications Manager.<\/p>\n Complete these steps:<\/p>\nTask 1: Add a H.323 Gateway to Cisco Unified Communications Manager<\/h2>\n
Activity Procedure<\/h3>\n
