Demo of Cellcrypt Mobile making an encrypted voice call over IP between a Google Nexus S on Wi-Fi and a Sony Ericsson Xperia Arc on 3G. I also show an encrypted a call between the Sony Ericsson Xperia and a Blackberry handset.

The call is encrypted using RC4 256-bit then AES 256-bit, authenticated using 2048-bit RSA & ECDSA, and key exchange uses Elliptic Curve Diffie Hellman & RSA.
