Today I will introduce you to some of the famous softphone based Indian Voip Providers. All of these providers requires to download a softphone client on pc along with a prepaid card of Rupee value. This card is available from many Pc stores in India also you could buy it online from provider. Most of these cards allow you to call many destinations at just 1Re per minute. Important point to note is that none of these cards allows you to make outgoing calls locally(India). This is due to fact that India is yet to allow its local Voip provider to terminate call domestically and all these providers are India Based ISPs(In India only Isps could offer voip services). Also these cards have an additional service tax of 12.24% above call value so a 1Re per min call cost 1.12Rs effectively.
