Because voice over IP uses one infrastructure for both voice and data, it can provide better and more enhanced service at a lower cost. A main reason why costs are cheaper is because Internet access is billed per megabyte rather than per minute or per second like regular phone calls. As such, the cost for data transfer is much less than that of time connected.

Telephones that use IP technology are much more economical, with the best deals providing unlimited inbound and outbound telephone calls to anywhere in the world for one low, monthly price that is all inclusive.
