Voice-scamming site “iSpoof” seized, 100s arrested in massive crackdown
These days, most of us have telephones that display the number that’s calling before we answer. This “feature” actually goes right back to the 1960s, and it’s known in North American English as Caller ID, although it doesn’t actually identify the caller, just the caller’s number.

received 2 calls from 956.377.2805 saying that the irs was filinga criminal law suit against me...no name and when you return call there was no one available.
