What is a PBX
A PBX (Private Branch Exchange) is essentially a company's private phone network system, allowing internal and external communication. Traditionally, businesses were connected to the public telephone company's central office for all call-related activities. Advancements, however, led to companies bringing this system in-house, creating the PBX. This setup allowed businesses to manage calls internally without needing separate external phone lines for every phone. Over time, these systems became automated, and now many PBX systems are hosted in the cloud, operating over the internet rather than traditional phone lines.
