Asterisk The Open Source PBX
33:06  - 2 years ago
Asterisk is a free software / open-source software implementation of a telephone private branch exchange (PBX). Like any PBX, it allows a number of attached telephones to make calls to one another, and to connect to other telephone services including the public switched telephone network (PSTN). "Its name comes from the asterisk symbol, *, which in Unix (including Linux) and DOS environments represents a wildcard, matching any sequence of characters in a filename." Asterisk is released under a dual license scheme, the free software license being the GNU General Public License (GPL), the other being a commercial license as to allow closed/patented code, such as the G.729 codec to work with the system (although the G729 codec may work with the free or commercial versions). Mark Spencer of Digium originally created Asterisk.
