3CX IP Phone System


3CX is a software-based IP phone system that works with SIP standard based IP Phones, SIP trunks and VoIP gateways to provide a full PBX solution. Offering a complete set of Unified Communications features, 3CX makes the installation, management and maintenance of phone systems easy.

Unlike other software-based PBX's, 3CX licences are charged by number of simultaneous calls required, rather than a number of users.

In order to become a 3CX reseller, you will need to become a registered 3CX partner, for more information, please visit the 3CX website.
