In iOS 10, Apple released a new API called CallKit. It lets VoIP calls show up as “normal” calls. So when you’d get a call from Skype, it would show up in full screen, instead of a notification, complete with the accept and decline buttons. And the calls would end up in the Phone app in the “Recents” tab.
The only problem is that if you use Skype a lot, they’ll basically end up taking over your Phone app. And personally, I don’t like that. It makes finding “normal” phone calls from the Recents tab much more difficult.
But don’t worry, there’s a way to disable this feature and go back to the old ways – the notification way.
Disable Integrated Calling in Skype
To disable the iOS 10 integrated calls in Skype, follow the steps below.
Step 1: Open the Skype app and tap on the “My info” tab.
Step 2: Select “Settings”, then swipe down the find the “Integrated Calling” option.
Step 3: Tap on the toggle to turn it off.
Manually Delete Past Calls from Recents
Now that new calls are disabled, it’s time to clear the old ones. Find the Skype call in the Recents menu, swipe “left” on it and tap on “Delete”.
No Such Option for WhatsApp or Facebook Messenger Yet
I went scuba diving in both Messenger and WhatsApp’s setting section but I couldn’t find anything to disable the CallKit functionality. Maybe they’ll add it soon. But for now, it’s only for Skype.
