First of all, VOIP is illegal in Nepal. I don't understand why NTC (NTA) is against the technology. Second, for broadband phone service like vonage, it require high speed internet and internet quality is very poor in Nepal. Even so called broad band is just broad band by name. I tried to use vonage from Nepal using Wlink broadband but internet speed is very poor. Do not use Worldlink broadband, worldlink is just cheating by saying its broadband. Their upload speed is normally just 16KBPS which is slower than dialup. So, the main problem is internet connection. So, if you can find any good broadband service provider in Nepal then vonage will work. I gave up because internet service wasn't good enough unless you want to pay high bill for those dedicated broadband service.
