Hi,
Each day new voip providers are entering this voip market, offering free minutes or free credits. Wipphone also offers free 30 minutes to any country. Though I have not used the service, but I guess it should also work for India.
To get 30 free minutes, you need to register with Wipphone, download their voip application (softphone). Now you will be able to make free calls worth 30 minutes. Its a free Pc to phone calling service.
Wipphone also offers business voip services. To call a wIPphone user, just dial his/her 10-digit wIPphone number.
To call a mobile or landline, just dial :
00+country code+telephone number
wIPphone to wIPphone calls are free. We will be coming soon with more such free calling offers.
