What is PBX.

What is PBX?

A Private Branch Exchange (PBX) functions as the main switching system for telephone calls within an organization. PBXs manage internal communications, and in addition, they mediate incoming and outgoing phone calls. Before the PBX came about, operators used a key system to connect calls manually from person to person via the Public Switched Telephone Network (PSTN). Eventually the technology evolved from manual to electromechanical, and key systems became outmoded.

PBX is responsible for value-added features such as voicemail, call queueing, multi-party conferencing, caller ID, conference calling, call forwarding, and more. Systems come in a variety of options such as hosted PBX, mobile PBX, software PBX, VoIP PBX, and hosted VoIP PBX. One benefit of a hosted service is that the service provider purchases and maintains the necessary equipment, saving thousands in out-of-pocket expenses for your small business.
