Session Initiation Protocol (SIP) Extension for Event State Publication
Abstract
This document describes an extension to the Session Initiation
Protocol (SIP) for publishing event state used within the SIP Events
framework. The first application of this extension is for the
publication of presence information.
The mechanism described in this document can be extended to support
publication of any event state for which there exists an appropriate
event package. It is not intended to be a general-purpose mechanism
for transport of arbitrary data, as there are better-suited
mechanisms for this purpose.
