SIP is separate from RTP. SIP sets up the signaling after which RTP flows to/from ports provided in the SDP of SIP. So with a pure SIP stack only, you cannot hear/talk, you only get to see session establishment. Once RTP is integrated, then voice will also work (along with whichever codec you choose).

So, as I see from the wireshark capture, there are no RTP messages to and from from Nitin and your UA. What my question is..were you able to talk and listen to Nitin with your SIP stack even without RTP stack. I am a student, so, I dont know much details..Still learning. If you were just able to establish sessions, is it expected that once RTP stack is also implemented we can exchange voice messages or can we use straight UDP for that. Thanks, Jyothsna You said you have not yet implemented the RTP stack for communicating voice.
