Hi All, A--------------------->B2BUA------------------------>B
A-Party does not support session. no Session_Expires,no Min-SE and no Supported:timer So no session refresh between A and B2BUA. When B2BUA supports timer. It sends INVITE to B with following details B2BUA-------INVITE---------->B Supported : timer Session_Expires : 840 Min-SE : 360 B2BUA<<--------200-OK----------B Supported:timer Session_Expires:240 Min-SE: 120 The B2BUA not obeying B' session_expires and starts timer on 840 sec. resulting B-Party sending BYE to the session after it's timer expiry. Should B2BUA should start timer on B's session_expires value (240sec) or it's own session_expires (840)?
