A Watcher Information Event Template-Package for the Session Initiation Protocol
RFC 3857, “A Watcher Information Event Template-Package for the Session Initiation Protocol”, is a Proposed Standard document published in August 2004 by J. Rosenberg. The canonical text is published by the RFC Editor.
Abstract
This document defines the watcher information template-package for the Session Initiation Protocol (SIP) event framework. Watcher information refers to the set of users subscribed to a particular resource within a particular event package. Watcher information changes dynamically as users subscribe, unsubscribe, are approved, or are rejected. A user can subscribe to this information, and therefore learn about changes to it. This event package is a template-package because it can be applied to any event package, including itself. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
