[OpenSIPS-Users] two UACs behind the same nat

[Nick Khamis]

If OpenSIPS is behind the same NAT (i.e., 10.10.12), the you don't
need the nat fixups or even the RTPProxy stuff. Try commenting them
out and checking. Also, are you "rtpproxy_answer"  in the reply route?
Finally make sure you are starting rtp proxy correctly:

rtpproxy -f -s udp:192.168.2.5:7789 -l private/public -m 20000 -M
40000 -u root root -F -d INFO LOG_LOCAL0_

Hope this helps,

Nick.
