I'm trying jitsi right now, I have an asterisk server and I would like to know if is possible if I add a contact of an extension is possible to have presence on it? now I don't know the state, maybe is this accomplished with hints? or something like that?
I've also jave some java code for IAX Java softphone (pure java) with gsm support, maybe some of this code could be meargeable to this project adding a new supported codec and/or a new protocol.
is there any documentation on how to develop plugins? and how to get started using netbeans?
