An INVITE-Initiated Dialog Event Package for the Session Initiation Protocol
RFC 4235, “An INVITE-Initiated Dialog Event Package for the Session Initiation Protocol”, is a Proposed Standard document published in November 2005 by J. Rosenberg, H. Schulzrinne, R. Mahy. It has since been updated by RFC 7463, RFC 8996. The canonical text is published by the RFC Editor.
Abstract
This document defines a dialog event package for the SIP Events architecture, along with a data format used in notifications for this package. The dialog package allows users to subscribe to another user and to receive notification of the changes in state of INVITE-initiated dialog usages in which the subscribed-to user is involved.
