IP (Internet Protocol) PBX (Private branch exchange) offers audio, video, and instant messaging communication through the TCP/IP protocol stack for its internal network.
VoIP (Voice over Internet Protocol) gateways can be combined with traditional PBX functionality allowing businesses to use their managed intranet to help decrease long distance costs, enjoy the advantages of a single network for voice and data and advanced CTI features.
Most of the cases it gives greater cost savings, better mobility, and increased redundancy.
