This caller has gotten through even though I've registered my number with the Federal Do Not Call Registry. Maybe they have to call from the same number more than once, not sure how it works. But i registered in 2005 and i didn't get any unwanted calls for about 12 years, until recently. I suppose they're getting better at hacking through, dunno. But it wouldn't hurt to go ahead and register your number. 1-888-382-1222 You only have to do it once, you have to call from the phone you want to register. And it's only for US residents. (I think it says that, it says something like that tho).
