[OpenSIPS-Users] Send rtp packet between two rtpproxy server

[Bogdan-Andrei Iancu]

Hi Kaushik,

As rtpproxy (by default) waits to first receive traffic (before pushing 
traffic back), there is a dead-lock created between the 2 rtpproxies - 
both are waiting for the other to send traffic.

What you have to do is, when using rtpproxy, to instruct rtpproxy to 
"trust" (not to wait, but to start using the IP without receiving) the 
IP in SDP - see flag 'r' :
http://www.opensips.org/html/docs/modules/1.11.x/rtpproxy.html#id293915

Of course, do that only if the SDP IP is a public one ;)
