I need to add voice chat to my Java application; Scenario is: we have one person, who wants to speak to other people, the application is over LAN (wire & wireless), i need a lib for example like this: lib.call(""), and at the client: lib.listen(""). The application is not a big one, so i don't want to integrate big voice chat libraries, I need a very small and simple one.

I found this one:https://github.com/jitsi/libjitsi , but I could find any good example for it!
