Re: Three tone .wav file said by Cyber2lz:I have the same three tone .wav file on my Voip line that I have on my pots line. Makes the autodialer think that this is not a working number. Before the DNC list started I had purchased this gadget from Radio Shack a few years back called the TeleZapper, which connected between phone and jack. Upon answering it would send a tone that supposedly duplicates the first tone of a non working number message tone that was supposed to make the autodialer of a telemarketer delete your number from their list. I did notice a sharp reduction in calls, not sure if I can credit the telezapper or not. |

This used to be the case many years ago. Now that most telemarketers/"unwanted callers" are using PRI (ISDN), they can obtain what's called a SIT code back. The SIT code is the phone company's version of what happened on the call. So if their phone system gets a Connect SIT tone, then hears the first two tones of a disco(nnect) message (or even the whole darn thing), the phone system/automated dialer will laugh and stay connected.
Telezappers are pretty worthless nowadays. Get a privacy manager if you want to avoid unwanted calls. It frustrates dialers and the people behind them, and they can't be easily tested-for like a Telezapper. |
