Except of course we in the UK have a really rubbish level of security on 
setting CallerID and is almost entirely down to trust and the person in 
charge of the phone system. Apparetnylthis will all change after 5G is 
rolled out but I have no idea why this is the case.

So there is a fair chance some poor Dutch person is getting a lot of 
complaints on his mobile and has no idea what they are talking about.
