[Kamailio-Users] Recording RTP session

Then I guess that rtpproxy is not enforced.

Take a look at the SDP of the outgoing SIP messages if the IP address in 
the c= line is rewritten or not.

I suppose it is relaying because if I comment out the rtpproxy related functions (force_rtpproxy) in my configuration file I don't hear anything, whereas if they are uncommented I can hear audio. How can I troubleshoot this? I've done tcpdump on port 7890 on my local interface and nothing is shown in the dump.
