Hello, I create a sip session with mjsip to an external voip provider. Then I transmit a test wav file over rtp to the provider using RtpManager.

The program runs with no errors and I answer the sip call. However, no audio is transmitted. When I diagnose the network traffic with wireshark, I see a bunch of RTP traffic from my localhost (behind some kind of nat) to the voip provider and nothing back.

After a while I get the ICMP error "Destination unreachable (Port unreachable)" from the provider to my localhost.

The software linphone works using the same localhost and voip provider - though it is using a different sip stack.

Any suggestions?

Thanks
