I see, you will be able to call and ”receive VoIP calls via a watchOS 9 app that uses CallKit”.

Hi, I also what to know more about this topic since I guess this is what Apple announced last year, that watchOS 9 will allow users to make VoIP calls directly from the Apple Watch through supported third-party apps. We have not found any documentation how to implement this functionality to the WatchOS framework? Thanks Emanuel
