The Open Source Asterisk Project

Asterisk is robust & mature enough to support a myriad of installations - from 5 seat cloud based phone systems to 500+ seat premise based contact center solutions implementing redundancy. The most liberating aspect of Asterisk is the features set and the associated licensing. While more features are added with every release, licenses for typical resources such as voicemails, extensions, and even auto-dialers no longer exist. Open Source telephony has truly revolutionized the PBX market while continuing to embrace legacy PBX features.
