Hi Younas,
when you have a call if you make a trace in your sip server with 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.
