What is a PBX Phone System?

PBX stands for Private Branch Exchange, which is a private telephone network used within a company or organization. The users of the PBX phone system share a number of outside lines for making external phone calls. A PBX also allows you to have more phones than physical phone lines (PTSN) and allows free calls between users. It also provides features like transfers, voicemail, call recording, interactive voice menus (IVRs) and ACD call queues. One of the latest tendencies in PBX phone system development is the VoIP PBX, also known as IP PBX, which uses the Internet Protocol to transmit calls.
