About Asterisk

Asterisk is an open-source framework for building communications applications, most commonly used to run IP PBXs, VoIP gateways, and conference servers. It turns a standard computer into a telephony platform supporting SIP, PRI, and analog interfaces, with call routing, IVR, voicemail, and call recording. It is aimed at developers, telecom integrators, and enterprises building custom voice systems rather than buying a turnkey product.
