3CX Phone System for Windows is an award-winning software-based IP PBX that replaces traditional proprietary hardware PBX. It is based on the SIP standard and supports most popular SIP phones, VoIP Gateways, VoIP service providers and PSTN phone lines. It is easy to manage by system administrators as it integrates well with Windows Network infrastructure.
“We have been very pleased with the overall capability of the 3CX telephone system within our business. With a Windows-based system, we have control over the phones and don’t have to pay for support from our old provider.”
