All calls from Viber and Skype are appearing as normal calls after updating to iOS 10. How do I disable this? After updating my iPhone 6 to iOS 10, all calls coming from Viber and Skype are appearing in the calls list as normal phone calls. Also, when I'm on a Viber call and a real phone call comes, I don't get notified. Before iOS 10 it used to mute Viber and give me a notification than someone is calling.  How do I return back to these settings?
I don't think it is possible to revert back to old settings now. I have opened a ticket with apple to get the users freedom to either use or not use. The setting like Setting -> Phone -> Service provider makes perfect sense. Lets see if apple provides this capabilities or not.
