Call Failed with FaceTime with macOS Monterey version 12.0.1
Everything is configured to make phonecalls with FaceTime via my iPhoneX. It works with High Sierra on my old Mac mini en it works with Big Sur on my new Mac-mini, but not any more with Monterey.
If I initiate a call on MacOS to my home phone, FaceTime immediately gives "Call Failed".
But my homephone starts ringing.
If I accept the call on home phone there is no connection.
Does anybody what is going wrong with Monterey?
