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.
