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. We are currently working on that feature.

This module works using SIP SIMPLE. The feature is still experimental.
