Kryptotel - Encrypted Voip

Kryptotel allows to make ENCRYPTED VOIP calls. It does use the TLS protocol to encrypt the information call (caller id /called id), and the ZRTP protocol to encrypt the audio communication with RSA certificates of 8192 bit and AES 256.
Kryptotel allows to dial and receive mobile voice calls that cannot be intercepted.
You can send/receive encrypted text messages, transfer pictures and place video calls one-to-one.
It is the only encryption application that guarantees high voice quality without delay even when it is used on mobile networks 3g/Umts.
Kryptotel works on every wifi/mobile 3g/satellite and everywhere there is an internet connection.
The application is ready to be used just after the download without any configuration or registration.
To make encrypted calls both parties should use Kryptotel but you can call with improved privacy even the normal phone numbers.
This App is available for Android and Ios (iPhone/Ipad).
