Hi, A small comment.
I don't think we in the draft should say that the UA forks. Because, I don't think the UA behavior is different from when it receives a 3xx response for e.g. an initial INVITE, is it? It uses the contact in the response to initiates new initial request. We don't call that forking, do we? Regards, Christer > -----Original Message----- > From: Vijay K.
