A SIP (Session Initiation Protocol for soft phones) library for Java 21+ which doesn’t suck (pun intended).

• Development status
• API stability
• Implementation details

There is a basic set of interfaces in the API. Using the API and a configuration, it is possible to connect (REGISTER) and disconnect (UNREGISTER aka REGISTER with Expires: 0). Incoming calls are being detected, but not yet routed to the SipEventHandler class.

There is basically no test yet, except a few which are being used for development.

None yet, goal is to have good stability before 0.4.0.

This library will make use of the Java 6+ Service Loader mechanisms. As a developer, you can code against the API only and have only the API in your class path whilst compiling. But for the runtime, the implementation will be needed as well.
