Best PBX Phone Systems for 2025

What is a PBX Phone System?

A PBX phone system for small business is a telecommunication system that manages internal and external phone calls for a company. Unlike traditional phone lines, PBX systems route calls between internal extensions, allowing multiple lines and departments to operate efficiently without requiring separate physical phone lines for each employee.

Modern PBX systems offer various features such as voicemail, call forwarding, automated attendants, and conference calling. Additionally, many systems today are cloud-based, which means they are hosted over the internet rather than being confined to an on-site physical device.
