between skype and voip, which one would give an even more economical pricing for someone who wants to make unlimited long distance international phone calls??? which one would be cheaper in the long run as far as unlimited long distance calls??? both use an internet connection but which one would prevail or override the other one? i live in central america and would like to call people the world over with unlimited minutes. wanna call argentina, canada, europe, japan, middle east, africa, new zealand, fiji, ect.... which one should i go with in that case if its between voip and skype? anyone have any suggestions? i merely want your opinion on this one. rsvp.
