The multitude of phone scam things is beyond annoying. They’re a national nuisance and a threat to people’s sanity and - literally, in many cases - their well being.
It’s impossible to believe that the technology to better protect us against that crap isn’t readily available. Over the past few years I’ve learned to recognize the types of calls to completely ignore, but I spend more time deleting “missed calls” and cycling through the same two or three bullshit recorded messages about my interest rates, etc., than I care to imagine.
And forget about identifying any one number as being the actual source. Like someone already said, they can make ANYTHING appear on Caller ID, including your own name and phone number. When I first started getting the occasional call from myself I took it as some kind of phone company glitch. Not so. And there will always be new numbers. You can “block” them to your heart’s content, but you are, in fact, blocking nothing. I tried it for a while. Don’t even bother. You’ll never know the actual originating number, and in all likelihood it isn’t even located in the US.
