Dial D for Disruption -- Want to build a phone company for $100? Give Mark Spencer a ring.

Spencer is the inventor of Asterisk, a free software program that establishes phone calls over the Internet and handles voicemail, caller ID, teleconferencing and a host of novel features for the phone. With Asterisk loaded onto a computer, a decent-size company can rip out its traditional phone switch, even some of its newfangled Internet telephone gear, and say good-bye to 80% of its telecom equipment costs.
A real bad news for companies like CISCO, NORTEL or AVAYA..
