The IESG has received a request from the Session Initiation Protocol Core WG (sipcore) to consider the following document: - 'A P-Served-User Header Field Parameter for Originating CDIV session case in Session Initiation Protocol (SIP)' <draft-ietf-sipcore-originating-cdiv-parameter-05.txt> as Informational RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2018-10-26. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract The P-Served-User header field is used 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 by defining a new P-Served-User header field parameter, "orig-cdiv". The parameter conveys the session case used by a proxy when handling an originating session after Call Diversion (CDIV) services have been invoked for the served user. This document also fixes the ABNF in RFC 5502 and provides more guidance for using the P-Served-User header field in IP networks. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-sipcore-originating-cdiv-parameter/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-sipcore-originating-cdiv-parameter/ballot/ No IPR declarations have been submitted directly on this I-D.
