The IESG has received a request from the Session Initiation Protocol Core WG (sipcore) to consider the following document: - 'A clarification on the use of Globally Routable User Agent URIs (GRUUs) in the Session Initiation Protocol (SIP) Event Notification Framework' <draft-ietf-sipcore-6665-clarification-00.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 2015-06-17. 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 Experience since the publication of the most recent SIP Events framework has shown that there is room for interpretation around the use of Globally Routable User Agent URIs in that specification. This document clarifies the intended behavior. This document updates RFC 6665. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-sipcore-6665-clarification/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-sipcore-6665-clarification/ballot/ No IPR declarations have been submitted directly on this I-D.
