VoIP lets you make toll bypass voice and fax calls over existing IP data networks instead of the public switched telephone network (PSTN). Today businesses that implement their own VoIP solution can dramatically cut national and long distance costs between two or more locations. As data communications emerged, companies paid for separate data lines so their computers could share information, while voice and fax communications were still handled by the PSTN. A corporation will often have two separate parallel networks often linking the same locations within the corporation. VoIP BASICS KCC 18th August 2002

A VoIP solution integrates seamlessly into the data network and operates alongside existing PBXs, or other phone equipment, to simply extend voice capabilities to remote locations without the cost of managing parallel networks.
