VoIP BASICS
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
Today, with the rapid adoption of IP, we now have a far reaching, low-cost
transport mechanism that can support both voice and data. 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.
