December 1,  the Federal Tade Commission has required all prerecorded telemarketing calls to include a "quick and easy" opt-out system to stop future call by the company. Typically for calls you answer, that means saying a certain word or press a number. Message left on your voice mail must have a toll-free number that connects to an automated opt-out system. Any prerecorded sales or fundraising calls that do not meet these criteria are subject to fines. File complaints at or call 1-877-382-4357 toll-free.
