There are a lot of people who make free Skype to Skype calls and this includes people in India.
There has been a new announcement from Skype which is that they will be ending the calling service from the Skype application to mobile phones and landlines within India. This change will take effect from November 10th 2014. The free Skype to Skype calls are still available also calls to other country landline and mobile phones.
I don't really understand why this is and neither has the reason been given.
