Caller ID and scams ☎

=> Circadian had a bank scam call with valid caller ID

I don't know much about telephony, but I've seen caller ID explained like this. If you make a call from a telephone (mobile or fixed) then the phone company knows the number you are calling from and can send it to the person you're calling. If your call passes between phone companies, they don't validate the caller ID because they trust each other. But phone calls can also originate from the internet, and when such a call crosses into the plain old telephone system, there's the same lack of validation. So you can claim to be calling from any number you like.

So don't trust caller ID.
