IP PBX

(Internet Protocol Private Branch eXchange) A telephone switch that supports voice over IP (VoIP). IP PBXs convert IP phone calls into traditional circuit-switched TDM connections for the PSTN. They also support traditional analog and digital telephones, allowing enterprises to migrate slowly to an all-IP telephony environment. See IP telephony and PBX.
