FTC issues rules on prerecorded calls

From the press release on the FTC web site:

FTC Issues Final Telemarketing Sales Rule Amendments Regarding Prerecorded Calls
Rule Will Halt Prerecorded Sales Calls Unless the Seller Obtains Consumer's Permission

The Federal Trade Commission today announced two amendments to the Telemarketing Sales Rule (TSR). One will expressly bar telemarketing calls that deliver prerecorded messages, unless a consumer previously has agreed to accept
such calls from the seller. The other related technical amendment modifies the TSR's method of calculating the maximum permissible level of "call abandonment."
