what is voice over internet protocol?What is the best voip provider?

It's just like a http(hyper text transfer protocol), but tranfers voice instead of text.The best VOIP providers r www.sgoope.org try this one.All calls r free absolutely, but u have to earn points for making calls.This is simple.you have to talk to ur friend using either skype or sgoope for 12maximum 12 min per call..u earn 12 points which r sufficient to make an international call for 5 minutes!!

A company called Vonage is the leading VOIP provider in the U.S., but I see you're in India. I don't know if Vonage operates in other countries or not.
