I am on the do not call list, but it's exempt for anyone you've done business with (I guess doing any business with a company gives them unspoken consent to contact you). Also exempt for non-profits and political organizations. I will be sure to tell them to take me off next time. I was so sleepy I couldn't even think straight. I don't have caller id or anything like that. This is from the website:

If I register my number on the National Do Not Call Registry, will it stop all telemarketing calls?
No. Placing your number on the National Do Not Call Registry will stop most telemarketing calls, but not all. Because of limitations in the jurisdiction of the FTC and FCC, calls from or on behalf of political organizations, charities, and telephone surveyors would still be permitted, as would calls from companies with which you have an existing business relationship, or those to whom you’ve provided express agreement in writing to receive their calls. However, if you ask a company with which you have an existing business relationship to place your number on its own do-not-call list, it must honor your request. You should keep a record of the date you make the request.
