PBX System
(Private Branch Exchange) - The main switching unit in a
multi-line digital phone system. The PBX routes calls to
voice mail, manages Direct Inward Dial (DID), station-to-station
calling, transferring, internal and external conferencing,
voice mail, music-on-hold (when applicable) and other manufacturer-specific
functions. PBX systems are usually digital systems designed
for a large number of users, although there are exceptions.
