Special Tone To Mess With Telemarketers

A blog called American Consumer News has a post on getting rid of telemarketers, even when DoNotCall.gov doesn't help.

The article tells about some gadgets that you can buy. They hook between your phone and the phone line. They play a tone that fools the telemarketing equipment into thinking that your phone is disconnected. This ends the call and erases your number from their system.

As a free alternative, the article also has a link to another site which has a recording of the tone. Just record this tone in the beginning of your answering machine message, and send the telemarketing call to the answering machine.
