TeleZapper - A Way to Avoid Telemarketers?

VeniDormi asks: "While watching TV on my TiVo, I actually stopped to see an ad for a device called 'The TeleZapper', which claims to foil tele-marketers by convincing their auto-dialers that your number has been disconnected. The FAQ is light on technical details, only mentioning that the device 'emits [a] tone briefly when the line is answered'. I'm hoping Slashdotters with more telecommunications expertise can enlighten me as to: how/if this might work and whether or not it is something I could reproduce with a sound card, say for recording at the beginning of my voicemail message. Could it be as simple as playing back the three shrill tones I hear when I dial a wrong number?" Ah, the telephone equivalent to SPAM. Too bad phones don't have the equivalent of procmail filters.

What's the point?

Wouldn't it just be a lot easier if, for example, when you hear a telemarketer on the phone just say "get bent" and then hang up on them?

Seems like a much less troublesome and a much more effortless solution to me! :)

OH CRAP

Ok, Ok, I admit it - i work for a telemarketing company. There, you happy?! I do it begrudgingly to support my "habit". Anyway, we use a number of methods, one of which being a predictive dialer running on SCO.

Our dialer has the ability to detect tritones - the "doo dee dii, the number you have reached...". There are several different tritones, and our dialer can distinguish between a "Changed Number" tritone, and a "Bad Number" tritone. I suppose that if this device sends out a tritone that matches the "Bad Number" tritone, our dialer wouldn't call it. You can, however, set your dialer to do whatever you like with those "dispositions". An unscrupulous company may set their dailer to pass those calls to the reps instead of dropping the line (We don't do that).

However, i happened to catch that commercial too, and it also says that it "...will automatically delete your name from their database". Of course, that's horse shit. It'll just dispo your record as bad number, what the company does with those is up to them.

Naturally i encourage everyone to check out their states' Do Not Call registry and add your name if you don't want to be disturbed (BTW, the laws about DNC'ing don't apply to things like election polling and charitable organizations - funny huh?)

So that's that!

Re:simple solutions also work

A simple solution for me is to have an *extremely* short answering machine message: "Please leave a message at the tone" said very quickly. My answering machine message is so short that the tele-spamming autodialiers don't recognize it as a machine and go ahead and connect to the telemarketer instead of disconnecting.

For a few months the result was a lot of messages saying "Hello . . . Hello . . . Are you there?" But the telemarketers then think it is a "broken" line, take the number off the list, and soon there are fewer telemarketers.

Simple and free.

Privacy Manger is extortion

[PD]

1) You get phone service from phone company
2) Phone company sells your information to other companies.
3) You tell phone company to make your number unlisted.
4) Phone company sells your information anyway.
5) Telemarketers start calling you.
6) You get "unknown caller blocking" and caller ID to stop telemarketers.
7) The phone company sells a service to the telemarketers that allows them to get around the unknown caller blocking.
8) You're getting telemarketing calls again, so PacBell says to you: pay us some money and we'll protect you from those telemarketers.
9) You send them their $3 a month and you're safe again, until the next time PacBell sells the telemarketers a service to let them get around the privacy manager.

It's a fucking extortion racket.
