Secure Voice GSM

Secure Voice GSM is a full duplex real time voice encryption solution, which allows you to talk and listen at the same time. Call authentication is made using an unbreakable RSA encryption based on 1024 bit asymmetric key algorithm using a random key. The voice encryption is based on ultra strong ARC4 algorithm and made using the RSA start session key. Your calls can never be violated by any third party and that is guaranteed!
