Chapter 38 Configuring Inspection for Voice and Video Protocols
MGCP Inspection
• The port on which the call agent receives commands from the gateway. Call agents usually listen to
UDP port 2727.
Note MGCP inspection does not support the use of different IP addresses for MGCP signaling and RTP data.
A common and recommended practice is to send RTP data from a resilient IP address, such as a loopback
or virtual IP address; however, the adaptive security appliance requires the RTP data to come from the
same address as MGCP signalling.
