ABSTRACT
This chapter (RFC 6502) specifies the notification mechanism for XCON (centralized conferencing) per RFC 6502. This mechanism reuses the session initiation protocol (SIP) event package for conference state. Additionally, the notification mechanism includes support for the XCON data model and for partial notifications. For clients that use SIP as the call signaling protocol (CSP), the XCON event package (RFC 6502) specified in this chapter MUST be used by the client for notifications of changes in the conference data. Thereby, SIP will also be used as the notification protocol between the notification client and the notification server.
