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

FreePBX is licensed under the GNU General Public License version 3.[2] It is a component of the FreePBX Distro, which is an independently maintained Linux system derived from the source code of the CentOS distribution, having Asterisk pre-installed. It is also included in various third-party distributions such as The FreePBX Distro and AsteriskNow.

FreePBX was acquired by in early 2013.[3] That firm was, in turn, taken over by Sangoma Technologies Corporation on Jan 2, 2015.

FreePBX is a community of developers and contributors who devote their work to making complicated phone system software easy to use and functional.

Many of the songs that are preinstalled are made by artist Macroform.


FreePBX can be installed as standalone software, or as part of a pre-configured FreePBX Distro that includes the operating system, the Asterisk PBX, FreePBX, and assorted dependencies:[4]

FreePBX is included in open source distributions such as The Official FreePBX Distro, AsteriskNOW, Elastix and RasPBX


FreePBX is written in PHP and JavaScript.[5] The first FreePBX release, version 0.2 (November 28, 2004), was named the Asterisk Management Portal (AMP). The project was renamed to FreePBX for trademark reasons, as Asterisk is a registered trademark of the Digium corporation (which is now also a subsidiary of Sangoma Technologies Corporation).

New releases of Asterisk have been accommodated by various updates to FreePBX. Updates have included 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.
