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.
The following modules must be loaded before this module:
No dependencies on other OpenSER modules.
The following libraries or applications must be installed before running OpenSER with this module loaded:
Default expires value to be used when the client doesn't supply one (in seconds).
Default value is "3600".

Meaning of the parameters is as follows:
domain - This can be either "registrar" or "jabber".
This function can be used from REQUEST_ROUTE, FAILURE_ROUTE.
