FreePBX: Why use FreePBX? All the Built-in Features

The phone/communication system is one of the first things to be updated as a company expands and introduces staff, clients, and vendors. When you hire more people, you’ll usually need a phone at each person’s desk and a way for them to communicate with one another. A PBX phone system, which stands for Private Branch Exchange, is used by many businesses. It’s best to think of it as a multi-line framework with extensions that allow for inter-office communication. Each internal extension has its own collection of outgoing phone lines for communicating with customers or those outside your house.
