Jitsi

If you want to make a personal video call by not being worried about espionage, then the service is a great alternative for other free, less secure VoiP services.

This chat and VioID conferencing client encrypts all sent data, such as any call - whether audio or video - or chat is protected from any other party that might want to access your data.

Jity can do audio and video calls, you can record phone calls, and also act as instant messenger to chat with your friends, even with a few users. All these data is encrypted and encoded using OTR.

Another great feature of this tool is that it is compatible with ICE and launched. In addition, it improves call quality by suppressing background noise or echo, making communication more natural and fluid without audio problems.

Jitsi does not only encode your messages and calls, but shows all of your security, your password is stored, encoded and which is protected by a master password. Note

Supports SIP, XMP / Jabber, AIM / ICQ, Windows Live and Yahoo Protocol.
