Hello all,
I'm trying to integrate rtpproxy with opensips and I can't seem to get rtpproxy to listen on any interfaces.  If someone could point me in the right direction I would greatly appreciate it :-)

I've provided some pertinent info below.  Please let me know if there is anything else that might prevent this from working.  BTW This is built from the recommended git snapshot and timeout patch.

# ps aux | grep rtpproxy
