I am facing the issue with one of my client, where my Termination is sending 183 with SDP but my UAC is unable to hear any destination country ringback. _______________________________________________ This is probably correct behavior by the client. There are no specifications of how the client should handle ringback. But the best practice is that the client should echo to the user any audio streams that it receives during the early dialog (at least, if the audio stream is not silence). In addition, if the client receives no audio streams but it has received a 180 (Ringing) response, the client should generate ringback to the user. In this case, the 183 would not trigger generation of ringback. In regard to the SDP, you need to observe whether the Termination is sending RTP and if the data in the RTP is not silence.
