[OpenSIPS-Users] Failed to engage rtpproxy for trunk

[Răzvan Crainea]

Hi, Michael!

"port 0" is returned by RTPProxy when an error is detected by RTPProxy, 
and usually the error is that it cannot bind the IP you asked to bind on 
(pub.lic.i.p). You should check the rtpproxy logs for more information.
