What is PBX?

A Private Branch Exchange (PBX) is a private telephone network used within a company or organization. Users of the PBX can communicate internally and externally using different communication channels like VoIP, ISDN or analog. A PBX connects internal extensions to the public switched telephone network (PSTN), allowing for features like call transfer, voicemail, call recording, interactive voice menus (IVR), and call queues.
