No, it doesn't stop it. BUT, when you get a call, whether recording or a real person and you've told them to not call and you're on the list you just need to make an official complaint. The form is on their website. I've done that with 3 companies. One of the companies called me 3 times a day and the other two called at least once a day. After I reported it to the Donotcall website, within 1 week the calls stopped!!!
