I have received several calls with that 000 exchange, 210-000-5567, 800-000-0001, 729-000-4282 and do not answer them anymore when I see 000. No ID is ever attached to these numbers. If I pick up before I see that, it is a recording that gets 1 second of my time before I hang up. How is this 000 exchange done? Is it ever legitimate?
