An IP (Internet Protocol) PBX (Private Branch Exchange) is a business telephone system designed to deliver voice over a data network and interoperate with the normal Public Switched Telephone Network (PSN).

In essence, VoIP (Voice over Internet Protocol) gateways are 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 CTI features.Business communications has always been a challenging arena for management, subject to cost, function, reliability, and other pressures and concerns. The emergence of VoIP technology, specifically application to PBX systems via IP based protocols, has provided an enormous opportunity for companies to reap many benefits.

Currently, each office uses its own PBX system and inter-office phone calls are routed through the PSTN and charged long distance and international rates by carriers. Most companies also employ workers on a part time basis who work from their homes. Those workers get reimbursed for telecommunication expenses they incur while performing their duties. It just makes business sense for companies to explore alternatives to consolidate their telecommunication systems and reduce costs.
