I really think that this draft should make the inclusion of the original non-2XX final response in the 199 MANDATORY by the forking proxy. This would be in a message/sip body as described in sectin 23.4/RFC 3261.
It should even include the Message body of the original response if present (some error codes have SDP bodies for example). Again, this would be embedded in the message/sip MIME. Otherwise, this ambiguity will sabotage potential use of this draft to solve wider problems such as HERFP. > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On > Behalf Of [EMAIL PROTECTED] > Sent: Friday, May 23, 2008 10:15 > To: [EMAIL PROTECTED] > Cc: [email protected] > Subject: [Sip] I-D ACTION:draft-ietf-sip-199-00.txt > > A New Internet-Draft is available from the on-line > Internet-Drafts directories. > This draft is a work item of the Session Initiation Protocol > Working Group of the IETF. > > Title : Response Code for Indication of > Terminated Dialog > Author(s) : C.
