Make free international calls to United States using the voip service providers listed below. We have compared the per minute calling rates to make international phone calls to USA from rest of the world. The choices here are unlimited and GoogleVoice is a clear winner here as its absolutely free as of now and comes with several features and excellent quality.
However, Google Voice is not available to people in all countries (like in India) so for people in such countries Smartvoip, rynga, 12voip, voipdiscount.com etc are a good option.
