What is Asterisk?

Asterisk is an open source framework for building communications applications. Asterisk turns an ordinary computer into a communications server. 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. Asterisk is free and open source. Asterisk is sponsored by Digium.

Today, there are more than one million Asterisk-based communications systems in use, in more than 170 countries. Asterisk is used by almost the entire Fortune 1000 list of customers. Most often deployed by system integrators and developers, Asterisk can become the basis for a complete business phone system, or used to enhance or extend and existing system, or to bridge a gap between systems.

VadaXchange is an IP PABX designed and built in New Zealand by Vadacom Ltd. It is based on Open Source Asterisk PBX, a leading open-source PBX project. With millions of installations worldwide and thousands of software developers and contributors, Asterisk is one of the most successful open-source projects.
