SIP for Presence

Status: RFC 3856
Date of last update: August 2004
Authors: J. Rosenberg
Current Document: RFC 3856
Summary: This document describes the usage of SIP for subscriptions and notifications of user presence. User presence is defined as the willingness and ability of a user to communicate with other users on the network. Historically, presence has been limited to ``on-line'' and ``off-line'' indicators; the notion of presence here is broader. Subscriptions and notifications of user presence are supported by defining an event package within the general SIP event notification framework. This protocol is also compliant with the Common Presence and Instant Messaging (CPIM) framework.
