"Upon receiving this, an autodialer will hang-up and remove the just-called number from the telemarketer's database, thus reducing future call volume."

- This is simply not a true statement. Usually, numbers that are dialed and determined to be a disconnected number or wrong number are re-dialed in future campaigns after the number is re-verified with the original source. The autodialer doesn't "remove the number from the database", it simply records the outcome as "disconnected" and the marketer will requeue it for calling in future windows. The only way to be "removed" from the database is to have your number flagged as a "Do Not Call" record, through the National DNC list or through writing or calling the marketer directly.

What is the purpose of this section? Wikipedia isn't a product directory, and the purpose of the article is to provide encyclopedic information about the product, not a list of ways to stop telemarketers from calling you.--142.59.60.210 20:18, 29 October 2006 (UTC)Reply

The above comment was mine logged out, I've since removed this section, as no one has provided any justification for it.--Crossmr 21:54, 24 November 2006 (UTC)Reply

The introduction to the article says that the TeleZapper plays either one or three tones. Under flaws, it says that the TZ only plays one tone, and since predictive dialers now listen for three tones, it's useless. One of these is wrong. Please fix! Mr. E.

The TeleZapper is actually ineffective with SIP-based predictive dialing for the following reasons:

• If the number called is a good number, the predictive dialer would receive a 200 OK message from the ITSP before the TeleZapper tone is actually played.
• The ITSP would normally send a response other than a 200 response if the number is actually disconnected.
• SIP-based predictive dialers are actually able to distinguish between good numbers and disconnected numbers without having to rely on disconnected tones because those details are available in SIP signaling.
• The TeleZapper tone normally does not alter the SIP signaling of the call.
• SIP-based predictive dialers are usually insensitive to disconnected tones, whereas analog predictive dialers are usually sensitive to disconnected tones. SIP-based predictive dialers generally rely on the SIP signaling responses from the ITSP, which are normally not audible, to detect whether or not a number is disconnected, instead of relying on disconnected tones.

You're probably right. The Telezapper is designed for analog lines and is from what, the late 1980's? Of course it's not going to work with anyone using SIP - and most telemarketers are moving in that direction as it's so cheap. I think we're seeing the beginning of the end of the TZ.

Based on the current (April 2019) telezapper.com website, it appears the original inventor of the TeleZapper is now operating the website as a non-profit consumer education site on the subject of telemarketing and telephone scams.--Theodore Kloba (☎) 16:20, 10 April 2019 (UTC)Reply
