re: Internet telephone advice(basic talk and others)

Best advice I can give is to purchase your own unlocked gateway device and then shop for plans from among the service providers recommended by the manufacturer. I started with an ObiHai unit that I bought to use with completely free google voice service. When I decided to upgrade to a more robust service, their web site was a good starting point for a list of reputable providers. I did eventually settle on CallCentric as my provider but I could drop them tomorrow and move to a competitor very easily. You can't do that with Magic Jack and Ooma.

Beware of so-called rankings and reviews of VoIP providers on the web. They're all paid advertising made to look like objective reviews.
