Trixbox

trixbox (formerly Asterisk@Home) was a software PBX based on Asterisk.

trixbox was initially released under the name Asterisk@Home. In October 2006 it was renamed to trixbox after Digium requested that its developers cease the use of the word "Asterisk"; the renaming was further justified by the fact that the product at that time consisted of much more than just Asterisk.

trixbox CE (end of life)
trixbox CE, the community edition founded by Kerry Garrison and Andrew Gillis, was completely free and was available under a GPLv2 license. It has been downloaded more than any other Asterisk-based PBX system according to SourceForge, with over two million downloads as of August 22, 2009.

trixbox CE was last updated with a beta release, and shortly after a blog post was made by Andrew Gillis, founder & leader of development stating he was leaving.

In October 2012, Fonality announced that they would no longer support or update trixbox CE, and would instead focus on trixbox Pro.

The FreePBX Project announced the availability of scripts to convert existing end of life trixbox CE systems to a current version of FreePBX, an open source PBX platform with ongoing support and development.

trixbox Pro
trixbox Pro is the commercial version trixbox. Unlike the community edition it contains components for which the source code is not available. These extra components are geared towards making the software better able to fulfill the needs of larger companies and call centers.

trixbox Appliance
trixbox Appliance is a server appliance available from Fonality which comes preloaded with either trixbox CE or trixbox Pro.
