PBX stands for private branch exchange and is a business phone system that has been in use in one form or another since the 1960s. A PBX phone system makes connections between internal telephones of an organization, so employees can call each other without having to use an outside line. If you’re using a phone system where each employee has their own extension, you’re using a PBX.

When PBX was first created, switchboard operators ran the in-house system. Now, the term PBX is used to refer to all types of complex, in-house switching systems.

Also called PABX (private automatic branch exchange) or EPABX (electronic private automatic branch exchange), PBX was originally created as a cost-saving measure for businesses. Instead of every employee having their own phone line through the public telephone network, which is costly, internal calls are handled within the company. External calls are routed through one of several trunk lines, which is why when you call out of a PBX system, your direct number does not appear on the caller ID of the recipient.

The hardware required for PBX is an investment, as it can save money in the long run. Leasing options are available so you can start reaping the benefits now. Hosted or cloud hosted PBX are also an option, but these systems are only as good as your network connection and service provider, and costs are actually higher in the long run.

Voice over Internet Protocol, or VoIP is another technology that has emerged in recent years that consumers and businesses are using. A VoIP system uses your internet connection to transmit the audio streams of you and the call recipient. Take advantage of the system with a native IP server for reliable service.
