[sipcore] Draft new: draft-mohali-sipcore-originating-cdiv-parameter-00

[<[e-mail]>]

Hi all,

Please find hereafter a new version of I-D, draft-mohali-sipcore-originating-cdiv-parameter-00 (was draft-mohali-dispatch-originating-cdiv-parameter-03).
https://www.ietf.org/internet-drafts/draft-mohali-sipcore-originating-cdiv-parameter-00.txt

Based on ADs and Chairs guidance, this draft is moved from DISPATCH to SIPCORE following the new charter of sipcore WG.

Abstract:
   This specification defines a new parameter of the P-Served-User
   header field in the Session Initiation Protocol (SIP).  This new
   "orig-cdiv" parameter defines the session case used by a proxy when
   handling an originating session after Call Diversion (CDIV) services
   has been invoked for the served user.  The P-Served-User header field
   is defined in RFC5502 to convey the identity of the served user and
   the session case that applies to this particular communication
   session and application invocation.  This document updates RFC5502 to
   add the "originating after CDIV" session case and to provide more
   guidance for using the P-Served-User header field in IP networks that
   were missing in RFC5502.

>From the discussion in DISPATCH, in this version of the draft, the syntax of the header could be improved as shown below:

 sessioncase-param        = ("sescase" EQUAL ("orig" / "term")) / "orig-cdiv"
 registration-state-param = "regstate" EQUAL ("unreg" / "reg")

This draft is not in the agenda for IETF 98 but comments are welcomed anyway.

Best regards,
Marianne
