History

In 1999, while a Computer Engineering student at Auburn University, Mark Spencer founded Linux Support Services. The high cost of buying a business phone system for LSS spurred him to use Linux and his programming skills to develop his own solution. He named it Asterisk, after the programming wildcard symbol and the ”star” phone key. It enabled phone calls over the Internet, providing an alternative to hardware-dependent PBX systems at a cost as much as 80% less.
Forbes Magazine characterized Asterisk's impact as “wreaking havoc on the multibillion-dollar phone equipment business,” and “disrupting the $7 billion market for office telecom switches” by enabling individuals and organizations to innovate in what was previously a vendor-locked marketplace. Asterisk-based business phone systems, like Digium's Switchvox, were the first of a new generation of VoIP-based communications solutions that would emerge to compete with the telecom giants like Cisco and Avaya. Reflecting the company's shift away from Linux support to applications and enhancements for Asterisk and the development of new communications solutions, Linux Support Services was renamed Digium in 2001.
Asterisk was released as open source by Spencer; today, the Asterisk Open-Source Software, the Asterisk community and forum, as well as an annual conference and expo, are all sponsored and maintained by Digium. Developers around the world continue to use Asterisk to create custom IP PBX systems, VoIP gateways, conference servers and other solutions for small and large organizations. They have also continued to enhance it, adding hundreds of features. It is estimated that Asterisk is currently being used by developers in 170 countries, is running on approximately 1MM servers, and is the foundation of communications systems for the majority of Fortune 500 companies.
