-https://en.wikipedia.org/wiki/Asterisk_(PBX)[Asterisk] is a software implementation of a private branch exchange (PBX).  In conjunction with suitable IP telephony hardware interfaces and network applications, Asterisk is used to establish and control telephone calls between telecommunication endpoints, such as customary telephone sets, destinations on the public switched telephone network (PSTN), and devices or services on Voice over Internet Protocol (VoIP) networks.  Its name comes from the asterisk (*) symbol for a signal used in dual-tone multi-frequency (DTMF) dialing.
