A Java implementation of the STUN and TURN and ICE protocols. This project is a continuation of the Stun4J initiative. The goal of the project is to provide VoIP Java developers with a means of handling NATs and firewalls.

The project is a joint effort of the SIP Communicator and TurnServer open source projects but is entirely based on standards and can be used with any other VoIP client or STUN/TURN server.
