[Users] rtpproxy + video issues

[Walter Schober]

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.
