Hi Aqs,
rtpproxy should  start relaying immediately to the port specified in the SDP. If the UA sends UDP packets from another source:IP port, it should update internal session data, so that all subsequent packets will be relayed to the proper IP:port. Otherwise it will continue to user the same IP:port specified in the SDP.

Is the IP in the SDP negotiation correct (the public one, and not the local one) ?
Have you had a look at the rtpproxy log ?

It looks a simple question but whats outgoing RTP packets destination? Is CALLEE IP present on that NATed destination?
Confirm that RTP Proxy determined that NATed IPs properly.
What did you receive in 200OK from CALLEE?
Check if engaged RTP ports are open in the flow?

            Hi Younas,

            when you have a call if you make a trace in your sip
            serverwith sngrep or tshark can you see the RTP packet ?
            you says "I have kamailio server behind nat with
            rptproxy.", so is it possible that the router in front
            your SIP server blocks the traffic? could you have a trace
            there?
            I mean the packets exit the rtpproxy but don't arrive to
            callee or just don't come out of the rtpproxy?

                Thanks for replying. Callee is actually a sip
                provider. I see no firewall or iptables rules on
                server to prevent rtp following towards callee.

                Is there anything i can do to see which thing is
                blocking rtps.

                Best

                    Greetings list,


                    I have kamailio server behind nat with rptproxy.
                    But i am getting no voice on the call. After
                    taking trace i could see that rtpproxy was
                    getting rtp packets but not packets was being
                    forwarded towards callee side.

                    Though i see in rtpproxy logs, packets being
                    relayed from caller side.

                    Does rtpproxy wait to receive a single rtp frame
                    from callee before fowarding that to callee?

                    Since, i am getting no rtp from callee. So, might
                    be rptrpoxy is waiting to learn source address of
                    callee side rtp, that is why it is not forwarding
                    rtp packets from caller towards callee.


                    Any pointer/suggestion is much appreciated.

                    Best Regards,

                    Aqs Younas
