VoIP PBX

A Voice over Internet Protocol (VoIP) private box exchange (PBX) is a business telephone system that provides services similar to a standard PBX, but does so over a company's LAN or WAN data network rather than through the circuit-switched networks used by the traditional Public Switched Telephone Network (PSTN).

Also referred to as an IP PBX, VoIP PBX systems can typically switch calls between VoIP on local lines or between VoIP and traditional telephone users in the same way a PBX does. A VoIP PBX system can be hardware based or can function entirely as a software system.
