Voice over Internet Protocol

VoIP is a new technology which allows users to verbally communicate through their computer. Essentially a telephone call made using the internet, VoIP is becoming increasingly more common in the business world due to its low costs, and easy set-up and maintenance.

Forget installation engineers and phone number changes, as long as you have a broadband connection, you can use VoIP any time, any where.

For businesses, this software is sure to eventually phase out the traditional phonecall. For as low as 4p for local and national calls, the economical potential is vast. With international calls often even less than that, VoIP is perfect if you are prone to long-distance telecommunication, or have offices, clients, partners, etc, overseas. What's more, calls made between VoIP users are typically free all you pay for is the standard internet service.
