Jitsi

JT is an open source video conferencing service that protects your privacy and protects you from espionage.

This chat, VoIP, telephone, and video conferencing service encrypts all information sent between two or more participants in the video conference. It will keep people from trying to hack or access your information secretly.

With Jitsi, you can make audio or video calls, record messages, and send your contacts group chat. All of these are encrypted and coded using OTR technology.

Another great thing about this tool is that it is compatible with the ICE and TURN protocols. Also, it improves the quality of the call and prevents background noise and echo for explicit conversations without interference.

In addition to encrypting your messages and calls, JetTs protect your password and privacy with a Master Password. This program is perfect for linking your favorite social network (Google Talk, Facebook, XMPP, and SIP).
