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

Look at rtpproxy module documentation,

http://www.opensips.org/html/docs/modules/1.9.x/rtpproxy.html#id249057

It mentions about a patch regarding timeout notification. Though this patch
can also be applied to latest rtpproxy code but opensips also maintains a
patched version of rtpproxy in its file repository.

I am not sure the reason for high CPU usage due to rtpproxy, in fact it
never happened to me, but then all my deployments are on real machines with
public IP. However, many fellows has faced this problem on VMs behind NAT.
I suspect this problem is more related to netfilter on bridge rather then
rtpproxy itself. Since rtpproxy consumes the greatest part of data traffic
that comes into VM in most of the cases, therefore it is blames for the
problem, while i think it is just a victim.

Thank you.
