3CX
3CX was founded in 2005 by entrepreneur Nick Galea who saw the need for an open standard software PBX for Microsoft Windows. With 86.7% of businesses using Windows as their operating system, the need for a software-based phone system which runs on Microsoft Windows was evident. With the PBX market being solely proprietary and devoid of any innovation for the past thirty years, businesses were increasingly becoming frustrated as they needed an open standard PBX that would be affordable, easy to use, innovative and software based.
