Product Description

Product Description

Not only does this handy gadget screen telemarketing calls for you, it also helps to ensure they won't keep trying to get ahold of you. The TeleZapper from Privacy Technologies plugs into any phone or phone jack. It works by emitting a special tone that makes your number appear disconnected to computer-generated calls. Eventually, as your number is eliminated from lists, the calls become a rarity, rather than routine. It won't interfere with manually dialed calls, answering machines, voicemail, Caller ID or Call Waiting. However, it may remove your number from the lists of organizations that use dialer computers. Easy installation. No monthly fees or service charges. AC adapter and phone cord included. Charcoal gray. No. MTZ800C. Imported. 1Hx4Wx4D"

When you've had your dinner interrupted by a telemarketer one too many times, treat your phone line and yourself to the Telezapper. It's a simple, one-time-cost solution to the problem of annoying telemarketing calls.

Here's how it works: Given that more than 90 percent of telemarketing calls are placed with computer assistance, when either you or your answering machine answers the phone, the Telezapper emits a special tone that tells the computer your number has been permanently disconnected. Telemarketing companies that use automated dialing systems typically remove disconnected numbers from their calling lists, and as your phone number is eliminated from more and more telemarketing lists, you'll notice fewer calls. Of course, not all telemarketers use predictive dialing systems, and those that do will undoubtedly work to evade the Telezapper, but it can be a partial solution.

For the most part, regular callers are unaffected by the Telezapper, but it may "zap" calls from other organizations that use the same predictive dialing technology (such as charities, pollsters, and automated emergency weather systems) and from callers who use certain types of calling cards. (For more information, click FAQ, or frequently asked questions, in the left navigation bar.)

In our tests of the Telezapper, installation took just seconds. We plugged the Telezapper into our phone line and our phone into the Telezapper and then connected the AC adapter. It was that simple. There are no moving parts to wear out and no batteries to replace.

We field-tested the Telezapper for several weeks, and during that time, we noticed a significant reduction in telemarketing calls. Of course, this was not a scientific study, and we cannot with certainty attribute our results to the Telezapper, but the device seemed to work well for us.

The Telezapper includes a phone cord, power adapter, and instructions. Privacy Technologies backs the device with a one-year warranty. --Mike Brown, with Ariel Meadow Stallings

Pros

  • Reduces telemarketing calls placed by predictive dialing systems
  • Doesn't interfere with most normal calls
  • Inexpensive, one-time-cost solution
  • Extremely easy to install and use
Cons
  • May "zap" some desired calls
  • Annoying beep every time the receiver is lifted

Customer Reviews

The telemarketers still call.

I didn't expect it to actually work all that well but I am amazed to say that it has worked incredibly well!

After I returned the TeleZapper that I bought from RadioShack because its annoying tones simply did not do the job promised, I was intrigued by the range of reviews other Amazon customers have encountered.
Being an engineer, I became curious. why didn't the TeleZapper work for me? Or, how would I know that it really worked? A friend mentioned that the Telemarketing industry can easily update their predictive dialers to ignore the TeleZapper's tone generation technique.
It turned out that this is the case for a widely used predictive dialer from Avaya, named "Mosaix". "The TeleZapper has absolutely no effect on the operation of the Mosaix Predictive Dialing System", according to an Avaya Sales Support Bulletin that I found on the Mosaix User's Group website. This finally cleared up my puzzlement about the TeleZapper.
I have also investigated the Caller Id systems that some phone companies offer to enable privacy management services. They seem rather complicated to set-up and to use. In addition, I would have to pay monthly fees for these services forever.
I am still looking for something to solve my unwanted telemarketer call problems. I have found another item on Amazon, named TriVOX. Its approach seems to be quite different. I am going to research it, and may post my findings on its review list.

Yes, telezapper will work in many cases & will reduce the # of solicitors. But, save your money - simply record the 3 tones for disconnected lines onto your answering machine - you WILL get the same results. I did and went from averaging about 6 calls per day to one. About 5 minutes of surfing led me to a web site that had these tones. The description about this box doesn't tell you exactly what it does for good reason - you don't need it!

Now that I work out of my house I became aware of all of the telmarketing phone calls we were receiving and it became very annoying.
I purchased a Telezapper and installed it on one of our phone lines in the house. Immediately I began to see the Telezapper do it's job since I got 4 calls the first day that were Zapped. You can tell when this happens because you get no sound when you answer the phone as the device signals the telemarketng computer that our phone number has been disconnected.
In just 2 weeks we notice a marked decrease in the number of unsolicited calls. We may only be getting one a day and we expect that number to decrease as the Telezapper continues to do it's job. The cost is insignificant compared to peace and quiet.

Telezapper has become my favorite product of 2001.
At our house, we had gotten into the habit of not even answering the phone, because there were so many telemarketing calls. (We'd rely on voicemail to communicate with friends and family.)
But now, when I pick up the phone, it's someone I want to talk to ... or there is a click telling me I just zapped another telemarketer, which I find very satisfying indeed. Sort of like when a mosquito hits one of those electronic bug catchers.
Others have written here that ($$$) is expensive for a device that merely emits a "disconnected" signal. Maybe the cost to manufacture is low ... but what's that got to do with it? Telezapper's value to me is many times greater than what I spent. It's worth it.
The fact that USA has the world's best phone system helps to make our country great. That an entrepreneur invented and sells the Telezapper makes it even greater.

Verified Purchase
Just follow the instructions. They suggest waiting 2 seconds before speaking into the phone if a "suspected" telemarketing call comes in. 95% of the calls are already disconnected be the time I say anything. Only one call that I can think of has gotten through, but I don't think it was as computer generated call. Great investment. Best to use if you have your answering machine at home and not through phone company.

I bought this hoping to end the deluge of computer generated telemarketer calls which interrupt meals and favorite T.V. shows etc. I paid the (...)price shown above. I had it plugged in for about 2 weeks and had the same amount of calls as before. It is supposed to zap a telemarketer if they repeat call you, but it does not. I have enhanced caller id so I know this is true. Myself and a co-worker had the same results and we both returned our telezappers to the place of purchase for refunds.

I have had the telezapper for 6 weeks now. And I am impressed how it woks. First thing you need to understand that it may take a little while for your name to get off all of those telemarketers lists. So for the first few weeks - the phone would ring - but then when I answerrd it - the telemarketer had already been disconnected by the time I said hello. It is definitely worth not to have to deal with saying "I am not interested" 9 times in the same phone call. Each week I have noticed a drop in calls. I am definitely sold on this product.

I really was't sure what I was getting with this. I mean the idea sounds great, no more calls from those annoying people. So I got it out of the box and hooked it up. This thing is tight. After pluging it in the calls seemed to almost stop. I do still get one or two annoying calls, but for the most part this thing is doing it's job. Give it a try, you'll be plesently suprised. It was cool.
