Most providers require you to have a custom telephone adapter that is pre-configured for their network so providing your own may not be an option. This technology converts the voice signal from your telephone into a digital signal that travels over the Internet. With normal internet protocols, you can have a network consisting of many routers (20 - 30 or more) which can result in a very high round trip time. You may be able to use your service wherever you travel as long as you have a broadband Internet connection available.
