Watch out for the userLocale and networkLocale
Get sure that the Fritz.Box name of the phone is the exactly the same as the "<line> -> <name>" field.
I use 9.0.4.
Hope that helps you and everyone who struggled as long as I did.
PS: Getting this error 'The contents of the attachment doesn't match its file type.' on my mac, that's why I have to post is as inline code, sorry.
