'VoIP is one of those mysterious acronyms that almost everyone has seen by now. If you've read or watched TV ads for Vonage or any of the other mushrooming broadband telephone services, or read about eBay's acquisition of Skype, you're familiar with it. You might have experienced it without even knowing it.
VoIP stands for Voice over Internet Protocol, a way of having a phone conversation over the Internet by sending packets of data rather than impulses, making it very different from the traditional telephone method. It became possible with the advent of high-speed broadband connections, and nowadays it's pretty much a fact of life, one that can, and will, significantly lower your phone bills.'
