FreePBX is a web-based open source GUI (graphical user interface) that controls and manages Asterisk (PBX), a voice over IP server.[1]

FreePBX is licensed under the GNU General Public License[2][3] and is a component of the FreePBX Distro (independently maintained Linux system derived from the source code for the CentOS distribution with the PBX pre-installed); it is also included as a key piece of various third-party distributions like The FreePBX Distro and AsteriskNow.

FreePBX was taken over by in early 2013;[4] that firm was in turn taken over by Sangoma Technologies Corporation on Jan 2, 2015.


FreePBX can be installed manually or as part of a pre-configured FreePBX Distro that includes the system OS, Asterisk, FreePBX GUI and assorted dependencies:[5]

The following open source distributions include FreePBX:


The first release, version 0.2 (November 28, 2004), was named the AMP (Asterisk Management Portal) project. The project was renamed to FreePBX for trademark reasons; Asterisk is a registered trademark of the Digium corporation.

There have been various updates to accommodate new Asterisk releases, new menus and support for additional capabilities such as voice mail, calling queues, fax, multiple languages, DAHDI and a local user directory.

FreePBX, the juggernaut of the Asterisk community. This interface (which is at the heart of many of the most popular Asterisk distributions, such as AsteriskNOW, Elastix, the FreePBX Distro, and PBX in a Flash), is unarguably a very large part of why Asterisk has been as successful as it has. With the FreePBX interface, you can configure and manage many aspects of an Asterisk system without touching a single configuration file. While we purists may like everyone to work only with the config files, we recognize that for many, learning Linux and editing these files by hand is simply not going to happen. For those folks, there is FreePBX, and it has our respect for the important contributions it has made to the success of Asterisk.
