In Brief - FRITZ!App Fon for iOS - CallKit is coming
Apple TestFlight: FRITZ!App Fon now supports CallKit
FRITZ!Box users who have FRITZ!OS 7 installed can register now for the TestFlight beta for the new FRITZ!App Fon (iOS).
With the new version for iOS, AVM is integrating support for Apple CallKit. CallKit means apps can deliver native notifications about incoming and outgoing calls, even if the user has the app in the background.
With the FRITZ!App Fon, it's easy to connect your smartphone or tablet with your FRITZ!Box over WiFi and use it as a landline telephone. This allows you to make calls via landline or the internet, benefiting from lower landline rates.
