Chapter 1. User's Guide
1.1. Overview
This module implements a presence server, i.e. entity that
receives SUBSCRIBE messages and sends NOTIFY when presence
status of a user changes. Currently the presence server can be
connected to registrar and jabber module so SIP users can see
presence of jabber users.
This module currently cannot work as a B2BUA, i.e. it cannot
subscribe to presence of users using SIP. We are currently
working on that feature.
