Hi, Cedric!
If you double checked the PCAP and you really are missing the flow from
RTPProxy to callee, I take your word for it. Pehaps the logging is
misleading.
Now, if RTPProxy does not send any packet to the callee, this means that
it doesn't get any packets from him. This means that there is something
wrong with the flow from callee to RTPProxy (192.168.157.141:12704 to
192.168.157.121:17226). If you see it in the PCAP on the RTPProxy
machine, it might be blocked at the firewall level?
Another thing that you could try: I saw that you are passing the "a"
flag to the rtpproxy functions. Do you really need it? Can you try to
remove it and test again?
Best regards,
Răzvan Crainea
