What does IP PBX stand for?

You may have heard about IP PBX, but what is it exactly? What does it do? Let me tell you all. The acronym “IP PBX” stands for Internet Protocol Private Branch Exchange.

A Private Branch Exchange (PBX) is a telecommunications system that handles the call control functionality of your telephones and fax machines while simultaneously managing your connection to the PSTN. (Publicly Switched Telephone Network).
