What is PBX?

A Private Branch Exchange (PBX) is a private telephone network used within a company.

It connects telephones within the organisation while sharing outside lines for making calls outside the organisation, so that each individual telephone user does not require a line directly to the telephone company.

Advantages of a PBX include cost savings for internal phone calls and the ability to feature services such as call forwarding and extension dialling.
