Title : Explicit Subscriptions for the REFER Method
Author : Robert Sparks
Filename : draft-sparks-sipcore-refer-explicit-subscription-00.txt
Pages : 6
Date : 2014-06-17
Abstract:
The 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 an extension to REFER to
remove the implicit subscription and replace it with an explicit one.
