Cisco Cisco IOS Software Release 12.2(2)XA

To enable debug traces for MGCP errors, events, media, packets, and parser, use the debug mgcp 
privileged EXEC command. To disable debugging output, use the no form of this command.

debug mgcp [all | errors [endpoint endpoint-name] | events {endpoint endpoint-name} | media 

{endpoint endpoint-name} | packets [endpoint endpoint-name | input-hex] | parser]

no debug mgcp [all | errors | events | media | packets | parser]

Debugging for DRiP packets is not enabled.
