Teleo
Teleo was a peer-to-peer Voice over Internet Protocol (VoIP) network founded by Wendell Brown, Andy Moeck and Craig Taro Gold in January 2004. The San-Francisco-based company's VoIP system enabled desktop and laptop PC users to send and receive phone calls over the Internet. Users could speak to other Teleo users for free, call traditional telephone numbers for a fee, and receive calls from traditional phones.
