How VoIP Works: 

MGW routes your phone calls over the Internet using Voice over Internet Protocol, rather than telephone lines. But even though your phone uses the Internet, it has nothing to do with your computer. In fact, your computer doesn't have to be on to use MGW. The people you call don't need to have VOIP or the Internet to get your call - just a phone. And when someone calls you, your phone rings as usual. VOIP is a newer technology to the communications industry. This technology allows phone service to be installed over any broadband connection. You get a local number and also get to avoid long distance phone calls.
