 PRIVATE BRANCH EXCHANGE Definition
We define PRIVATE BRANCH EXCHANGE |
PRIVATE BRANCH EXCHANGE - A private phone switch used within a company that allows inter-company phone calls without using outside lines. It also connects to one or more outside POTS lines, which are often partitioned off into outgoing lines, incoming lines, or lines that can be used for both purposes. PBXs today use digital connections for inter-company calls, thus you must use digital phones as opposed to standard analog phones (and modems). A PBX is typically a large and costly piece of machinery maintained and/or supported by the company that sold the PBX. There are various options that can be added onto PBXs for call reporting, call management, and voicemail. |
