Abstract
This document defines a conference event package for tightly coupled
conferences using the Session Initiation Protocol (SIP) events
framework, along with a data format used in notifications for this
package. The conference package allows users to subscribe to a
conference Uniform Resource Identifier (URI). Notifications are sent
about changes in the membership of this conference and optionally
about changes in the state of additional conference components.
