hi there guys,
we have a 2921 with a VIC2-4FXO out on a site in India the clients phones register over a managed MPLS network to a centralised CUCM cluster
the client wanted to break local calls out of analogue lines; the router is registered as an MGCP gateway to the CUCM cluster
to breakout locally they use 9 when making a call; the call goes out correctly ringing can be heard and the call connects
once the call connects though there is no audio at all have got the client to dial mobile and landline numbers to test
the two interesting things i see in the debug are below
------
voip_rtcp_stop_session: ERROR - Dest IP Addr=0, no RTCP pkt sent
voip_rtp_get_gccb:Error, no gccb for callID
-----
i have attached scrubbed router config, voice port summary and debug for an outbound call for reference
-----
any pointers would be gratefully recieved

Is the phone able to ping the IP assigned to interface GigabitEthernet0/1.6 assigned on the gateway?
