An IP ([[Internet Protocol]]) PBX ([[Private branch exchange]]) is a business telephone system designed to deliver voice or video over a data network and interoperate with the normal Public Switched Telephone Network ([[PSTN]]).

[[VoIP]] (Voice over Internet Protocol) gateways can be combined with traditional [[PBX]] functionality enabling businesses to use their managed [[intranet]] to help reduce [[long distance]] expenses, enjoy the benefits of a single network for voice and data and advanced [[Computer telephony integration|CTI]] features or be used on a pure IP system which in most cases give greater cost savings, greater mobility, and increased redundancy.

An IP-PBX can exist as a hardware object, or virtually, as a software system.

==Function==
Because a major part of IP PBX functionality is provided in software, it is relatively inexpensive and easy to add additional functionality, such as [[Conference call|conferencing]], [[XML-RPC]] control of live calls, [[Interactive voice response]] (IVR), [[Speech synthesis|TTS]]/[[Speech recognition|ASR]] (text to speech/automatic speech recognition), [[Public switched telephone network]] (PSTN) interconnection ability supporting both analogue and digital circuits, [[Voice over IP]] protocols including [[Session Initiation Protocol|SIP]], [[Inter-Asterisk eXchange]], [[H.323]], [[Jingle (protocol)|Jingle]] (extension of [[Extensible Messaging and Presence Protocol|XMPP]] protocol introduced by [[Google Talk]]) and others.
