    Hi Everyone,

    I'm working on a project that I am completely lost on and I need some education and guidance. I have to write a application to detected keys pressed by caller. As example when caller calls, system ask from the caller to press 1, 2, 3 then when he/she pressed that number, system has to perform some task according to the choice. I have know clue about how to do this.

    ...anyone got any hints, ideas, educational links or tips?

    Thanks a lot!

    I'm not really sure how you want to do this. But I have a few ideas. Since key have different tone, you would need to identify the different tone. And program the case table according to the tone. You could do this whit a voice recognizing program or something like this. Or have your program make a sample and analyses the frequency of the tone. And then give a value for your case table.

    Second, the key probably send some kind of signal, that could be interpreted like when you press a PC keyboard. This one is simple if you can get the HEX value of each key. And them make the case table for your program using those value.
