Digium’s history is rooted in a desire to open up the most advanced and flexible business communications technologies to organizations of all sizes. For nearly two decades, Asterisk, the open source toolkit, has empowered developers to design and build their own telephony applications in a way that best fits the goals of their organization. Asterisk was developed by Mark Spencer, and born out of his need as a small, start-up entrepreneur to find an affordable communications solution. Using Linux, Asterisk was built as an alternative to expensive phone systems that were based on proprietary hardware and inflexible software. Asterisk quickly grew into the leading open source telephony project, putting a more powerful communications solution into the hands of businesses, nonprofits, governments and communities around the world.
