Asterisk is the world's most widely used open source software, a product of more than a decade of work by a community of over 80,000 developers worldwide. Digium is the sponsor and maintainer of this free open source software that has caused a worldwide telephony revolution.

By harnessing the power of collaboration, Asterisk taps the global talent pool of developers, systems integrators and open source enthusiasts. The result is software that can be customized to a degree impossible with proprietary systems, at a drastically lower total cost of ownership.

Having so many people working on the project means that Asterisk now supports multiple applications, ranging from standard PBX implementations, to full-featured UC solutions like Switchvox, to advanced database-integrated contact center solutions for global businesses.

Asterisk powers IP PBX systems, VoIP gateways, conference servers and other custom solutions. It is used by small businesses, large businesses, call centers, carriers and government agencies, worldwide. It is used by almost all of the Fortune 1000 customers and is deployed in more than 170 countries. It even powers an entire country's communications system and provides disaster recovery communications.
