Voice Gateways and Session Border Controllers

An engineer needs to manually register an analog port with Cisco UCM by using the MGCP protocol. Which commands are required?

  • A no mgcp mgcp call-agent 172.16.1.252 ccm-manager config server 172.16.1.252 ccm-manager config ccm-manager mgcp ! dial-peer voice 1 pots port 1/0/0 shut no shut !
  • B mgcp mgcp call-agent 172.16.1.252 ccm-manager config server 172.16.1.252 ccm-manager config ccm-manager mgcp ! dial-peer voice 1 pots port 1/0/0 shut no shut !
  • C mgcp ccm-manager config server 172.16.1.252 ccm-manager config ! dial-peer voice 1 pots application MGCPAPP port 1/0/0 !
  • D mgcp mgcp call-agent 172.16.1.252 ccm-manager config server 172.16.1.252 ccm-manager config ccm-manager mgcp ! dial-peer voice 1 pots application MGCPAPP port 1/0/0 shut no shut !
Explanation

A manually configured MGCP analog endpoint requires a POTS dial peer bound to the analog port and assigned the MGCP application (MGCPAPP). The gateway must also enable MGCP, specify the Cisco UCM call agent, configure and download the Cisco UCM configuration, and enable ccm-manager mgcp; resetting the port initializes the added endpoint.
