The IESG has received a request from the Session Initiation Protocol Core WG (sipcore) to consider the following document: - 'An Extension to the Session Initiation Protocol (SIP) for Request History Information' <draft-ietf-sipcore-rfc4244bis-09.txt> as Proposed Standard 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 2012-09-20. 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 This document defines a standard mechanism for capturing the history information associated with a Session Initiation Protocol (SIP) request. This capability enables many enhanced services by providing the information as to how and why a SIP request arrives at a specific application or user. This document defines an optional SIP header field, History-Info, for capturing the history information in requests. The document also defines SIP header field parameters for the History-Info and Contact header fields to tag the method by which the target of a request is determined. In addition, this specification defines a value for the Privacy header field that directs the anonymization of values in the History-Info header field. This document obsoletes RFC 4244. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-sipcore-rfc4244bis/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-sipcore-rfc4244bis/ballot/ No IPR declarations have been submitted directly on this I-D.
