Hi ,
I have a gateway connected to a PABX via sip trunk. Gateway is connected to another site which has an IVR. The protocol from my gateway to IVR is H323. Now when i place a call from PABX to IVR. DTMF doesnt work. I have tried making all dial-peer DTMF-RELAY RTP-NTE. But still it doesnt work.
When I ask the customer they say they are supporting RFC2833.
The following is my configuration Dial-peer 10 and 55 point to my IVR (malasiya), sip dial-peers point to PABX in singapore site (my current site):-
