DIAL D FOR DISRUPTION

Excerpt: Want to build a phone company for $100? Give Mark Spencer a ring. In a research park outside the low-key bustle of downtown Huntsville, Ala. Mark Spencer finishes his barbecue and resumes wreaking havoc on the multibillion-dollar phone equipment business. 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. Not good news for Cisco, Nortel or Avaya. Article: forbes, Related: Asterisk
