Asterisk is the leading Open Source software implementation of a telephone private branch exchange (PBX); it allows attached telephones to make calls to one another, and to connect to other telephone services, such as the public switched telephone network (PSTN) and Voice over Internet Protocol (VoIP) services. It can be software only, moving calls around via IP, or it can support a large variety of relatively inexpensive hardware interfaces to directly tie in with existing TDM (Time Division Multiplexing) equipment.
