I currently am running Kamailio in a WSS configuration with sipML5.  I use rtpengine to convert a RTP/SAVPF packet to a RTP/AVP packet as the destination server only supports AVP or SAVP.

RTPEngine has no issues rewriting the packet going out, the SIP session comes up and handshakes correctly to start the session.  Then the remote server sends the RTP stream back and I'm having issues getting Kamailio or RTPEngine or something to take the RTP stream, process it back to SAVPF and send it back out the WSS port.  I see no RTP data come from Kam/RTPengine going towards the remote server.

On the server side, I do see STUN being called and the sipML5 bind successfully but that's it.

Both the destination and server sit without firewalls in the way so the problem has to be what I'm doing in Kamailio.

My config is located here:

Thanks for any assistance!
