I have 2 SJphone behind the same NAT (I know that it's a restricted con NAT).
UA1 ----> (NAT 1) --------> PROXY | | UA2 <-----(NAT 1)<-------------
I've configured my openser.cfg to use Mediaproxy (installed in the same pc) if 1 or 2 pc are behind NAT (in this case both of my pc). But when I call from UA1 to the other and I accept the call with UA2, the RTP stream doesn't flow through the Mediaproxy but it's direct from UA1 to UA2.
Any clue? thanks daniel
