I did that with a
If (loose_route())
if method==INVITE
#this is an reinvite
unforce_rtpproxy()
...
re-aquire rtpproxy ressources.
Then you will get new ports from rtpproxy and everything is working fine :-)
At least it did for me.
I guess it's a bug in the rtpproxy, if a ressource is again requested with
additional ressources as video.

Hi,
most probably the reason is your are not performing properly from script
the NAT traversal for sequential request (especially for INVITE).
to be sure that;s the case you may try using rtpproxy for all cases
(nated or not) to see if this solves your problem.

Hi,
I am trying to deploy a openser solution supporting NAT traversal. So far
I have dome some testing with rtpproxy and have yet to look into the
media proxy solution. I have IP Phones that support both audio and video
calls and as a requirement the setup should be able to do NAT traversal
for both audio and video streams.
Initially two phones connect with only audio streams active. Any side can
activate a video request in which case a reinvite is sent to the other
side indicating video codecs in the SDP. In case, any one or both sides
are nated the server should rewrite SDP port to route traffic through
itself. I tried to use a config with nathelper and rtpproxy, Initially
audio ports and IP in the SDP are rewritten correctly but when one phone
sends a reinvite for video the video port in the 200OK reply message is
not rewritten and is sent as received. This results in the video being
sent to an incorrect port on the server (running rtpporxy) and therefore
no video is relayed.
