a GUI latter for MGCP calls however when trying to apply a filter for the
packets based on the “VoIP Calls” section for some reason my
experience has been that it doesn’t work (haven’t tried on any
newer releases of Wireshark in a while).<o:p></o:p></span></font></p>

10.0pt;font-family:Calibri;color:blue'>You’ll likely need to write your
own using libpcap or BASH/Perl scripting around tethereal. The main challenge
is that the endpoint IDs in an MGCP messages are only sent in the MGCP requests
but not on the response which means you need to find all the TIDs/IPs/etc
belonging to the endpoint transactions you’re interested in and then find
all the associated response packets based on TIDs and IPs.<o:p></o:p></span></font></p>
