Basically, because there is no verification/validation surrounding caller id - https://en.wikipedia.org/wiki/Caller_ID_spoofing
Why is it still possible to spoof caller id?
Except caller id / phone number is easily spoofed
but you can't rely on the phone number reported by caller id - they're very spoofable.
I'm guessing but the problem is source phone number spoofing. If Caller ID worked correctly 100% of the time and 100% of the time you get a fraud/spam/etc call you could complain and the authorities knew who owned the phone number it would be harder to operate the fraud. And with personal cryptographic attestation you could reliably link a phone number to a person.
They could trivially spoof the number they're calling from to match.
ummmm, caller ID are easily spoofed, no?
This won't work since Caller ID is too easy to spoof.
It should not be possible to spoof caller ID. This hole is what allows all of this. Nobody would do this if you could reliably report them or call them back.
This is no longer a valid tactic. The phone number can, has, and will be spoofed.
