In UAE, Skype users had to pay for a VPN service to make calls from their Skype to phones on top of the subscription charge or the Skype credit. Recent reports indicate that this restriction is no longer applicable and Skype users are indeed able to call Indian phone numbers with their subscription as of Jan 2015, which is good news for Skype users.
Update: Google voice users can already make Hangout to phone calls without the need for a VPN through Gmail, provided they have bought calling credit from Google.
