What is a PBX?
PBX, an acronym for Private Branch Exchange, is a private telephone network used within a business or corporation. Users of the PBX share a certain number of outside lines for making telephone calls external to the PBX.

This hardware is generally very expensive and requires on-going support and maintenance which can add to already high set up costs.

When an outside call is required, an access number is dialed first, usually a “9” (in the United State
