I mean, I've done all that before but I don't see anything besides the SIP traffic and DNS queries.

of course "tcpdump -n udp" works too if you do not have ngrep around
(e.g. Centos)

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.
