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

This is totally understandable!!!

Is this not available yet as is for the rtpproxy module (i.e.,
rtpproxy_offer/answer(ci)...)?

According to someone who hard coded the public IP address in MediaProxy code:

http://lists.sip-router.org/pipermail/users/2008-January/015111.html

This was done so that MediaProxy would bind to the local IP, and
broadcast the public IP. But as you correctly mentioned, media related
SDP directive (i.e., c=) is managed by OpenSIPS. Not sure if the "cie"
flags are available for mediaproxy. Hope someone from AG and RTPProxy
could help out.

Sorry for the hijack!!! But this is kind of related? :)
