See, when you break the full name down and you’ll get the meaning. PBX, short for Private Branch Exchange, is a private telephone network used within a company or organization. The users of the PBX phone system can communicate internally (within the company) and externally (with the outside world), using different communication channels like VoIP, ISDN, or analog.
