The FTC has approved the publication of a Federal Register notice announcing the extension of the public comment period on two proposed amendments to the Telemarketing Sales Rule (TSR). The two proposals were announced in a previous Federal Register notice on October 4, 2006. One proposal would explicitly prohibit using prerecorded messages in telemarketing calls answered by a consumer (unless the consumer has given prior written consent to receive such prerecorded message calls). The other proposal would change the method of calculating the maximum allowable rate of call abandonment from a "per day per calling campaign" standard to a "per thirty days per calling campaign" standard. The public comment period will now expire on December 18, 2006.
