The Session Initiation Protocol (SIP) REFER request, as defined by
RFC 3515, 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 that remove the implicit
subscription and, if desired, replace it with an explicit one.
This document is a product of the Session Initiation Protocol Core Working Group of the IETF.
This is now a Proposed Standard.
