I mean, that if you have 2 UAC behind the same NAT and they do STUN queries and discover it public IP (Eyebeam does this if you don't disable STUN support), you will not see traffic going throught mediaproxy, because from OpenSer point of view, they are capable of exchanging RTP together without mediaproxy intervention. You have to do ngrep captures during this test and look at the SDP bodies to check if media IP's changes on INVITES and replies. Also I suggest you to learn who to use sipspy, that will let you take full-visual-trace of SIP traffic and learn how things flow throught your proxy. P.D.: Please, do not use gmail anymore or configure it to work as a compliance email client. -- Saludos. Raúl Alexis Betancor Santana Dimensión Virtual S.L.
