History
3CX Phone System for Windows was developed by 3CX and first published as a free IP PBX product in 2006. The product was intended to provide a VoIP solution for use in a Microsoft Windows environment.
The first commercial edition of the product was launched in 2007. Reviews of the product have noted its easy configuration, management, and hardware compatibility. Smith on VoIP commented in a blog post about 3CX that it was very easy to use, but did not have all the features its competitors provide. In 2009, it was featured on the internet TV show Hak5.
