[OpenSIPS-Users] NAT - Unable to solve RTP Problem

[Ovidiu Sas]

If you want to properly disconnect calls when there's no BYE and the
RTP stream has ended, then you need to use the patched rtpproxy
version provided by opensips.  Some of the patches has been integrated
into the rtpproxy git repo (don't know if all of them are integrated).
Also, I know that the latest rtpproxy version from git has some issues
(high CPU load).  The stable 1.2.1 works just fine (but that one
doesn't have the timeout notifications):

I don't see why MediaProxy would not work behind NAT.  After all,
there are no IPs embedded into the RTP packets and it should just work
as long as the proper port forwarding is enabled and the proper IP is
set inside SDP by opensips.
I think an enhancement to mediaproxy module that would allow forcing
the IP to be used in SDP would solve this particular issue.
