Configuring FXS and FXO Analog Ports
You use the same commands to configure both Foreign Exchange Service (FXS) and Foreign Exchange
Office (FXO) ports. The gateway recognizes the type of voice interface card that is installed in each
voice network module and applies the configuration you enter based on the port position you specify in
the command.
To enable FXS or FXO ports with MGCP, enter the following commands:
Gateway(config)# dial-peer voice <number> pots
Gateway(config-dial-peer)# application MGCPAPP
Gateway(config-dial-peer)# port <portnumber>
To use these commands, replace <number> with a unique numeric ID, and replace <portnumber> with
the port identifier in the form slot#/voice module#/port#. Use the application MGCPAPP command to
place the port under control of the Cisco CallManager MGCP call agent.
