The Private Branch Exchange has gone full circle as a term. Originally having started as an organization's manual switchboard operated by the telephone operator or just simply the operator, they have evolved in to VoIP centers that are hosted by the operators or even hardware manufacturers. These modern IP Centrex systems offer essentially the same service, but they have moved so far from the original concept of the PBX that the term hardly applies at all.
