Fonalityâ€™s tixbox CE, which is essentially an extension of Asterisk, clocked 2.8 million downloads in 2008 compared to the â€˜parentâ€™ open source platform Asterisk which had some 1.5 million downloads during the same period. trixbox CE (Community Edition) is more of a complete application. It provides administrators the tools necessary to deploy a fully-functioning phone system.
A good analogy would be Asterisk being an engine and trixbox CE a complete car. There are several extended Asterisk systems available in the market where developers are offering an alternative to licensed IP PBX software. Over 18% of all the IP PBX extensions configured worldwide now run open source IP PBX.
On a cumulative basis, trixbox CE has been downloaded about 6 million times.
While Digium (Asteriskâ€™s owner) is in the business of selling hardware on the back of their Asterisk â€˜channelâ€™, most of Fonality's revenues are generated by PBXtra (a turnkey system for SMBs) and trixbox Pro (software used by Fonalityâ€™s indirect reseller and OEM channel to build complete solutions). Trixbox Pro is promoted by large distributors such as Dell Computers.
According to industry estimates Asterisk accounts for nearly 85% of all open-source PBX implementations. Out of these, Fonality reckons that trixbox CE makes up around 60% to 75% of all Asterisk-based, open-source deployments.
Some of the well known vendors that develop for and/or integrate with Fonality trixbox CE platform include Zoiper, QueueMetrics, Sangoma, Rhino, Aastra, Polycom, CounterPath, Broadsoft, Broadcom, and Pika.
