Mark Spencer, Founder And CTO, Digium
As the inventor of the Asterisk open-source IP-PBX platform, Spencer is responsible for what may be the open-source software that is having the biggest bang in the SMB market. Asterisk, along with Spencer’s open-source development prowess and passion, have paved the way for Digium to deliver robust enterprise-class VoIP solutions with its Switchvox product to SMBs at a fraction of the cost of its larger rivals. Today Asterisk is downloaded nearly 5,500 times a day and has a community of 63,000 participants. Spencer will no doubt push the Asterisk open-source movement and Switchvox to new heights in 2010.
