A Session Initiation Protocol Event Package for Registrations
RFC 3680, “A Session Initiation Protocol Event Package for Registrations”, is a Proposed Standard document published in March 2004 by J. Rosenberg. It has since been updated by RFC 6140. The canonical text is published by the RFC Editor.
Abstract
This document defines a Session Initiation Protocol (SIP) event package for registrations. Through its REGISTER method, SIP allows a user agent to create, modify, and delete registrations. Registrations can also be altered by administrators in order to enforce policy. As a result, these registrations represent a piece of state in the network that can change dynamically. There are many cases where a user agent would like to be notified of changes in this state. This event package defines a mechanism by which those user agents can request and obtain such notifications. [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.
