Even is somebody has the means to eavesdrop on your phone conversation, they won’t hear much - only static and meaningless noise. This is how Xaos Gamma works.
It is a Polish encryption phone, designed and manufactured by TechLab 2000. The device is very user-friendly as it doesn’t require any knowledge about encryption - you just use it like a normal phone. It has all the basic functions although it won’t take pictures, record video or send MMS messages. Xaos Gamma is targeted at business users, lawyers, doctors and everyone who appreciates the importance of confidentiality.
