Here's the answer to all our prayers. Telemarketers almost exclusively use "autodialers" to make their calls. One out of a thousand will have live reps doing the dialing. When these dialers connect (you answer the phone) they listen for any "tones" generated. If no "tones" are detected they then transfer the call to one of the reps in a call center. "IF" the autodialer hears the 3 beeps from dialing a "DISCONNECTED" number, the number that was just dialed is automatically "REMOVED" from their list. Below is a link that has this "tone" plus the verbal message. You DO NOT need the verbal message. Download or copy the "DISCONNECTED" MP3 or WAV file to your desktop. Create or change the greeting you have when someone calls you and you're not available. At the VERY BEGINNING of your message place the 3 tones (NOT THE VOICE MESSAGE) then continue with your usual or normal greeting. The autodialer will hear the tones and BINGO, your number will be removed since they think it's a disconnected number. DONE. In a few weeks you will be removed from all the lists. Of course you may have to explain the tones to the callers you DO want to speak to but that's a small tradeoff. Pass this info on to anyone you know that gets junk calls or even help post this on these websites. GET RID OF JUNK / SPAM CALLS.
