Tired of telemarketers bothering you? Then check out this page and download the “sit.wav"  file. If you put this sound at the beginning of your answering machine message, then the predictive dialing software used by the telemarketing industry will mark your phone number as disconnected, taking you off their call list. Another source that I read claimed that only the first tone of the series is necessary, but I’m not sure about that. I plan on trying this as soon as I get home, and although it may confuse legitimate callers leaving messages at first, anything that will reduce the number of intrusive solicitors calling me is well worth it in my opinion.
