A complete 3CX Phone System for Windows consists of the server software, soft phones or SIP hardware phones, and a VOIP Gateway to connect your existing phone lines. A VOIP provider can be used to leverage low cost calls across your user network.

The system can use the existing computer wiring (and share the network point with the computer) and can be installed on an existing, non-dedicated Windows server (no need for Linux!) or run as a virtual machine. Say goodbye to expensive, proprietary, phone system expansion modules and costly phone bills!
