Open Source’s (VoIP) Call for Change

Location: D137 Level: Intermediate
Average rating: ***..
(3.20, 5 ratings)

Open source, for all its success penetrating corporate, education, and even government computing environments, has spent more than a decade waiting at the telephony industry’s door. The landscape is finally starting to change, and it’s evolving quickly.

In this session, Mark Spencer, founder of Asterisk, will discuss the new and emerging role of open source VoIP; the new business model enabled by open source; cutting edge “mash up” unified communications solutions being developed with Asterisk that combine VoIP, mapping, social networking, and sales force applications.

He will also discuss the important role the open source community is playing in bringing new Asterisk-based solutions to consumers and businesses alike; solutions ranging from applications that let your plants call you when they need watering, to business telephony features and functionality that rival proprietary communication giants like Cisco and Avaya.

Mark Spencer


Mark Spencer founded Digium®, Inc., in 1999 as Linux Support Systems while still a computer engineering student at Auburn University. When faced with the high cost of buying a PBX for the company, Spencer simply used his Linux PC and knowledge of C code to develop his own PBX. This was the beginning of the worldwide open source phenomenon known as Asterisk®.

As Asterisk gained in popularity, Spencer shifted his business focus from Linux support to supporting Asterisk and opening up the telecom market. Mark renamed the company Digium and transformed the fledgling upstart into the leading open source telecommunication provider in the world today.

As the Chairman and CTO of Digium, Mark Spencer continues to drive the strategic vision and technology direction of the company as well as focus on the development and growth of the Asterisk Community at large.

Spencer is widely regarded as the pioneer of open source telephony and gives frequent keynote addresses to large technology audiences.
