What is the primary function of 3CX?

The primary function of 3CX is as a software-based private branch exchange (PBX). It serves as a complete phone system that allows businesses to manage their calls over the internet, rather than relying on traditional telephone lines. This software solution provides flexibility for businesses, enabling features such as voice calls, video conferencing, texting, and integration with other business applications.

3CX operates on various platforms, making it accessible on various devices like desktop computers, smartphones, and web browsers, enhancing the mobility and efficiency of communication. The software-based nature of 3CX allows for easier management and scaling, as new features can often be added or updated without the need for physical hardware changes. This stands in contrast to other options that represent different functions or systems entirely.
