[OpenSIPS-Users] custom presence bodies

[Răzvan Crainea]

Hi, Tito!

The Content-Type indicates how to read and parse the Message body. This 
is a mandatory header, and without it the client can't know how to 
interpret the body.
The Event header is used by opensips (and clients) to figure out the 
event that happened.
The idea is that the clients will subscribe for a particular event 
(presence, or conference in your case) and when that event happens, 
OpenSIPS will send notifies only to those clients registered for that event.

Best regards,
