The IESG has received a request from the Session Initiation Protocol Core WG (sipcore) to consider the following document: - 'Explicit Subscriptions for the REFER Method' <draft-ietf-sipcore-refer-explicit-subscription-02.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 [email protected] mailing lists by 2015-06-17. Exceptionally, comments may be sent to [email protected] instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract The Session Initiation Protocol (SIP) REFER request, as defined by RFC3515, triggers an implicit SIP-Specific Event Notification framework subscription. Conflating the start of the subscription with handling the REFER request makes negotiating SUBSCRIBE extensions impossible, and complicates avoiding SIP dialog sharing. This document defines extensions to REFER to remove the implicit subscription and, if desired, replace it with an explicit one. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-sipcore-refer-explicit-subscription/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-sipcore-refer-explicit-subscription/ballot/ No IPR declarations have been submitted directly on this I-D.
