What is Asterisk?

Asterisk™ is Open Source software with which you could turn a normal PC into a VoIP PBX. By the installation of special ISDN cards or analog adaptors you can also connect ISDN and analog phones beside SIP-capable phones.

Since the installation and configuration of an Asterisk PBX for professional use is quite complex, several manufacturers offer preconfigured systems that do not differ externally from a traditional PBX.
