Called & hung up before the answering machine picked up. Just block. Don't answer or call back, or press anything to be removed from the call list. All of these actions just confirm to scammers that a real person answered and the number is "good". Then they will sell the number to others, and you just get more calls from more scammers.
Being on the no call list prevents law-abiding companies from calling you with solicitations. It will not prevent scammers; they're already breaking laws and don't care that you're on the do not call list.
