Asterisk is a complete PBX in software. It runs on Linux, BSD, Windows (emulated) and OS X and provides all of the features you would expect from a PBX and more. Asterisk does voice over IP in four protocols, and can interoperate with almost all standards-based telephony equipment using relatively inexpensive hardware.
The asterisk derives from the two thousand year old character used by Aristarchus of Samothrace called the asteriskos, â», which he used when proofreading Homeric poetry to mark lines that were duplicated. Origin Adamantius is known to have also used the asteriskos to mark missing Hebrew lines from his Hexapla.
