[OpenSIPS-Users] Proxying Presence?

[Anca Vamanu]

Hi Stephen,

It depends on the type of presence you want ( depending also on what I 
supported by you phones). If the phones are able to send Publish 
messages ( if they support Presence Agent), then you can configure the 
presence server feature in OpenSIPS. Then you will have to handle the 
Subscribe and Publish messages on the server - see this tutorial: 
http://www.opensips.org/Resources/PresenceServer. Also in the default 
script you have the lines for the presence server, just uncomment those 
and comment some other lines - follow the indications in the commentaries.
If you want to implement end-to-end presence, then you have to forward 
the Subscribe to the other client - just call lookup() and t_relay() for it.

Regards,
