The disadvantage of cryptophone is that it only works with other cryptophones. To work around this, we turn mobile phones from "voice" phones into VOIP phones. Using the SIP protocol for VOIP and IPsec/L2TP or Openvpn as our VPN, Leigh Honeywell and Paul Wouters connect their mobile phones fully encrypted to an Asterisk PBX server.
