Explanation:
PBX is an acronym for private branch exchange. It is a private telephone network service that allows users to communicate by making or taking inbound and outbound calls using a gateway, voice mail, transfer calls, call queues and recording.
In an office, employees having a PBX telephone can call other employees in the same office regarding official work.
The callers have to dial a particular extension number so that the intended receiver gets the call.
Example of an extension number is 111-5001 and 111-5002, with a central number as 111-5000.
Hence, the telephone network used in this office is the PBX system.
