jitsi.org Secure Open Source Video Calls & Chat

ice4j.org The Interactive Connectivity Establishment (ICE) protocol combines various NAT traversal utilities such as the STUN and TURN protocols in order to offer a powerful mechanism that allows Offer/Answer based protocols such as SIP and XMPP to traverse NATs. This project provides a Java implementation of the ICE protocol that would be usable by both SIP and XMPP applications. The project also provides features such as socket sharing and support for Pseudo TCP. This project is maintained by the Jitsi community. Use Jitsi's dev mailing list for questions and discussions. Javadocs for the ice4j API are available here.

Work on this project is graciously funded by the NLnet Foundation. Thank you!
