Can someone please point me to a web source for .WAV (or other computer audio format) files of telephone Touch Tone signals? I am particularly in the so-called “disconnected” signal. This is the familiar series of three tones, each higher than the one before it, sounded over a period of about one second, that indicate having reached a disconnected number. This is apparently the technology behind the “Telezapper” apparatus that purports to automatically remove your number from telemarketer’s computer lists. Basically, I want to build my own 'zapper. Uncharacteristically, Google has been of little help here.

Sorry, found it. Should have searched here (SDMB) first anyway.

So, might you perhaps post a link, for the benefit of those who come behind you?

Me, for instance?

Oops. I’m NOT looking for the “disconnected” tri-tone. I want the simultaneous-dualtones you hear when you press the various button keys.

Oh you want the DTMF tones. There are 16 of them. Let me Google and see if I can find them. Do you need all 16 or just the 12 used on a standard touch-tone telephone?

Dude, phone phreaking is sooo 1980. . . I know, I know.  
So do you put this in an answering machine message? How does this work? [Can we discuss this on the board?]

Thank you, thank you!

I have routines that will dial a phone, but they insist on obtaining a #@^%W@Q dial tone first. What I want, of course, is to be able to send the equivalent of “push 3 for blahblah”, in mid-call (i.e., without disconnecting, without obtaining a dial tone)-- and the only way to do that that I can think of is to play the tones over the modem. And I can do that.

you can get your meodem to send DTMF tones directly with AT commands:

> [@](#):
>
> To send DTMF tones after you have dialed a remote computer you must type ATDT\<#\>, just like when you are dialing a number. If you are already connected to the remote computer you must type +++ATDT\<#\> to put your modem in command mode. To return to online mode just type ATO. The +++ are escape characters which put your modem in command mode. If you want your modem to send data then you must return to on-line mode, using the ATO command.
