Many of those annoying prerecorded telemarketing calls will be history starting Sept. 1.

The Federal Trade Commission said Thursday that it is banning these "robocalls" to consumers, unless the telemarketer has written permission from a customer that he or she wants to receive these calls.

FTC Chairman Jon Leibowitz says American consumers have made it "crystal clear that few things annoy them more than the billions of commercial telemarketing robocalls they receive every year."

Violaters will face penalties of up to $16,000 per call.

Exceptions include calls that deliver information such as flight cancellations and those from debt collectors, politicians, charities, banks, phone companies and others.
