Private Branch Exchange (PBX) is an internal telephone exchange or switching system implemented in a business or office. PBX allows for handling of internal communications without the use of paid Public Switched Telephone Network (PSTN) service, also known as Plain Old Telephone Service (POTS). A Voice over Internet Protocol (VoIP) PBX, which takes advantage of existing LAN cables, can further reduce costs by removing the need for separate telephone cabling infrastructure in a building or office. VoIP endpoints are specialized hardware devices or application programs that enable VoIP calls from computing devices. VoIP gateways are network devices that convert voice and fax calls, in real time, between an IP network and PSTN/POTS.
