http://www.donotcall.gov/ Q: If I register my number on the National Do Not Call Registry, will it stop all telemarketing calls? A: No. Placing your number on the National Do Not Call Registry will stop most, but not all, telemarketing calls. You may still receive calls from political organizations, charities, telephone surveyors or companies with which you have an existing business relationship. Telemarketers calling to solicit charitable contributions are not covered by the registry, but if you make a request to a specific organization that they not call you, they are required to honor your request. If they subsequently call you again, they may be subject to a fine of up to $11,000.
