With increasing number of voip service providers coming up, how do you compare voip with calling cards? For example, I have found out that Sunrockets offers 17c/min to Kathmandu and 32c/min to other towns. There is another provider that offers 19c to KTM and 26c to rest of the country. I have never used VOIP phones. I wonder if the service is good and clear. Anyone who used VOIP and liked it compared to phone cards? pros and cons please .. from VOIP users. Thanks.
