IP PBX

Short for Internet Protocol Private Branch eXchange, a telephone switch that supports VoIP. An IP PBX provides services similar to PBX services, but over data networks like a LAN or WAN rather than circuit-switched networks. IP PBX typically can switch calls between VoIP on local lines or between VoIP and traditional telephone users in the same way PBX does. IP PBX may also be seen abbreviated as IPPBX or IP/PBX.
