[Users] rtpproxy + video issues

[Bogdan-Andrei Iancu]

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.

regards,
bogdan
