Apple has recently introduced CallKit, a new framework available to developers that allows them to integrate their VoIP apps with the native Phone app user interface. In essence, this is a great addition that puts VoIP apps at virtually the same level as normal phone calls. Incoming Skype or WhatsApp calls, for example, are now displayed fully on the Lock screen, which is an improvement compared to how these calls were handled prior to iOS 10. Likewise, any call placed or received with a supported VoIP app will be logged into the Phone app like a normal call.
This tight integration of VoIP apps and the native Phone app UI can have a downside for some users who might prefer not to see their recent Skype calls history show up in their Phone app. If you're one of these people, we'll show you exactly how to stop Skype from showing recent calls in your Phone app.
