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.
3CX licences are charged by number of simultaneous calls required, Unlike other software-based PBX's, rather than a number of users. Supporting 4 to 1024 simultaneous calls and a range of versions available, you can create a scalable, low cost solution to meet your needs. Systems can also be expanded with the addition of the 3CX "SBC" which allows your phone system to be linked with remote offices as if they were in the same building. Perfect for remote offices or working from home.
