What’s the traditional PBX phone system?


A traditional PBX (Private Branch Exchange) phone system is a type of telephone network that has been used by businesses for decades.

It is a physical piece of hardware that is installed on-site at a business location and is responsible for routing incoming and outgoing calls to the appropriate extensions within the company.


The traditional PBX system is designed to handle voice communication over the Public Switched Telephone Network (PSTN) using analog or digital signals. It can support a range of features such as call forwarding, voicemail, and conference calling.

The PBX system allows businesses to have multiple phone lines and extensions, which are typically assigned to individual employees.


A traditional PBX phone system requires specialized technical expertise to install, configure, and maintain. It also requires a significant upfront investment in hardware, which can be costly for small businesses.

However, many larger businesses continue to use PBX systems because they offer a high level of reliability and control over their telephone communications.
