The IESG has approved the following document: - 'A Message Summary and Message Waiting Indication Event Package for the Session Initiation Protocol (SIP) ' <draft-ietf-sipping-mwi-04.txt> as a Proposed Standard This document is the product of the Session Initiation Proposal Investigation Working Group. The IESG contact persons are Allison Mankin and Jon Peterson. Technical Summary This document describes a SIP event package to carry message waiting status and message summaries from a messaging system to an interested User Agent. Using SIP-Specific Event Notification, a Subscriber User Agent (typically an IP phone or SIP software User Agent) subscribes to the status of their messages. A SIP User Agent acting on behalf of the user's messaging system then notifies the Subscriber whenever the messaging account's messages have changed. The mime type application/simple-message-summary is defined for these notifications. Working Group Summary The working group reviewed and supported advancing this specification. Protocol Quality The event package has been checked against RFC 3265. The document was reviewed for the IESG by Allison Mankin.
