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. It does not work with Skype.

TeamTalk – a software conferencing system which enables a group of people to collaborate and share information. During a conference people can talk using their microphone, see other people using their webcams, share files, show desktop applications, play music, etc.

Unlike other popular conferencing applications TeamTalk comes with its own standalone server. This means you do not depend on a third party to host your conferences. In other words you’re in complete control of your community and can choose who can participate.

TeamTalk supports multiple video sessions so it’s possible to see video of every user in a channel.
Any application running on your computer’s desktop can be shared with other users. This can be used for doing online presentations.
File sharing – users can see which files can be downloaded in the channel they’re participating in. Each file is listed with a name, its size and who uploaded the file.

The TeamTalk client application contains a list of publicly available TeamTalk servers which you can connect to and use freely. Some might, however, prefer to run their own server and for this TeamTalk comes with its own standalone server available for both Windows, Mac OS X and Linux. Running your own TeamTalk server allows you to configure exactly how you want your server to look and who should have access to it.
