The IESG contact persons are Allison Mankin and Jon Peterson. Technical Summary 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. Working Group Summary The work on this extension began in the SIMPLE working group, because the requirements were generated in the context of presence information. As a result, there was a great deal of review of the serviceability of the extension, before it went to the SIP WG for review of its generality and conformance to SIP guidelines. There was some debate on architecture, but there was a strong support for advancement of this document. Protocol Quality There have been many reviews of the specification, and it has been well managed by its editor. Allison Mankin reviewed the specification for the IESG.
