What is the PABX system and how it is useful?

Most offices around the world rely heavily on communication systems. A reliable internal communications system like the PABX telephone that allows employees to interact without relying on external elements is frequently one of the first things implemented in new corporate headquarters and small business offices alike, regardless of company size.

Before the internet, business communications were mostly handled by building traditional landline phone systems at the office, with tens of metres of cable connecting the stationary phones to provide smooth and fast connectivity. However, these systems were vulnerable to a variety of external variables, including provider-side power outages and price hikes by telephone service providers.

Implementing private branch exchange (or PBX) systems enables the majority of commercial communications capabilities. Previously, managing the company's employees' calls and transferring them via analogue means required a room of operators. These individuals were also responsible for handling all incoming communications and routing them to the appropriate recipients.


With the introduction of the PABX system or Private Automatic Branch Exchange, all of that changed. Businesses have seen a significant reduction in communication expenses, as well as enhanced interconnectivity and response times. You'll understand the fundamental distinctions between PBX and PABX after reading this article, as well as how to deploy these solutions in your own organisation.

PABX-enabled phones have rendered operator rooms obsolete, as the identical functions could have been performed at the touch of a button on the same phone from which the outgoing call originated. Internal calls for PABX users are free. These solutions were initially out of reach for most people. Traditional PBX systems were kept in use while the original switchboard-based technique was improved. Electronic switching for call forwarding or transfer became the norm in most businesses over time, even in those without a fully automated PBX.

The emergence of the capacity to electronically switch between calls without the use of manual operators enabled the creation of a PBX solution. This breakthrough paved the door for the creation of a telephone system that eliminated the need for people to answer and transfer incoming calls entirely.


The necessity for rapid, dependable connectivity should be valued above all else in our increasingly interconnected and interdependent society. This is especially essential in corporate settings, where a few minutes (or even seconds) of reluctance or a long session start-up might cost thousands of dollars. To get the best potential results, an increasing number of businesses are turning to voice over IP (internet protocol) technologies. It might be difficult to choose the best communication solution for your company if you don't know what to look for.

Without getting too complicated, PABX systems use extension numbers, which are assigned to each individual phone in a certain business, in their most basic form. For example, if you wanted to call a coworker who works next door, all you had to do was dial his extension number on your phone with PABX installation.
