When you’ve had your dinner interrupted by a telemarketer one too many times, treat your phone line and yourself to the Telezapper TZ 900. It’s a simple, one-time-cost solution to the problem of annoying telemarketing calls. Based on the enormously popular classic TeleZapper, the newer TeleZapper TZ 900 offers the advantages of a slimmer profile, built-in battery power, and an advanced three-tone mode.
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 continue their work to evade the TeleZapper, but it can be a partial solution.
