RTSP Inspection
– Gateways—Identifies the IP address of the media gateway that is controlled by the associated
call agent. A media gateway is typically a network element that provides conversion between

other packet networks. Normally, a gateway sends commands to the default MGCP port for call
agents, 2727.
– Call Agents—Identifies the IP address of a call agent that controls the MGCP media gateways
in the call agent group. Normally, a call agent sends commands to the default MGCP port for
gateways, 2427.

group of gateways and call agents.
