Hi Tech People ,
we are trying to record a MGCP Audio Stream from A third Party Voice Recorder. we have VG400 integrated with CUCM via MGCP Protocol for PSTN Calling. we have no problem in recording the SIP and SCCP streams on same voice recorder. we can see the Communication between CUCM and Voice Gateway via MGCP using 2427 port from the following capture but Voice Recorder is unable to record a audio conversation.
