Zfone – a secure VoIP phone software product which lets you make encrypted phone calls over the Internet.

– Interoperates with any SIP/RTP phone, auto-detects if encryption is supported by other endpoint
– Available as a “plugin” for existing soft VoIP clients, effectively converting them into secure phones
– Available as an SDK for developers to integrate into their VoIP applications
– IETF has published the protocol spec as RFC 6189, and source code is published

Zfone runs on Windows XP and Vista, both 32-bit and 64-bit versions. Zfone will encrypt audio and video for Apple iChat calls on Mac OS X. Zfone has been tested with these VoIP clients: X-Lite, Gizmo (audio, no video yet), XMeeting, Google Talk VoIP client, Yahoo Messenger’s VoIP client (for audio), Magic Jack, and SJphone.
