Also healthcare providers, though they seem to have finally wised up. They would call me from poorly configured phone systems (so unrecognizable caller id) and the first thing they would ask is to confirm full name and date of birth.
Patterns like this do a great deal of damage in desensitizing folks and making them accept dangerous patterns that get exploited by scams.
So asking people to take the step to confirm the call is legitimate won’t work- they can’t tell until they’ve already terminated the call. It’s useless for purpose imo.
I imagine it is doing something with STIR/SHAKEN along with how many other times similar calls have been flagged as spam calls.
I have reported at least a thousand different scam calls over the past two years and so my blocked number list is so large it freezes the phone for a minute or so while it loads. Still the scammers persist…
