    Detect numbers

    Hi!

    Can somebody give me a suggestion about the following
    problem:

    I would like to realise an application which detects
    if a certain phone button is pressed during a phone
    call. Its not easy to explain but its something that
    we all know from this phone queues: if you want help
    press one, if you would like to speak to Mr. X press two...

    Kind regards!

    Re: Detect numbers

    Hi!

    Yes I would like to detect keys but not
    the one of my phone but those which are
    pressed during a phone call by the caller =)

    I think DMTF is the keyword....

    Is there a module or function or
    do I have to write it by my own???

    hi freaky_911
    really sad that there is no such direct modules are available for the purpose what you want you can write an extension for that .moreover you can go for any other algorithm like a keylogger.
    thanks and have a feedback.

    Do you mean that person A calls you and then person A is pressing those keys? Then you (your application) would detect those key presses, translate into numbers and do something in your phone? That's in YOUR phone? Caller A is controlling YOUR phone during a phone call?

    Great idea, never thought about doing it like that...

    Well, digital number tones are using different frequences. Then it's just a question of listening (any) audio during a phone call, identifying when key press happens vs any other local background noise and detecting the exact audio frequencies (two simultaneous, I recall). Should be easy, right

    Very close. The difference is that DTMF system has direct access to phone audio channel without any/too much noise. Detecting DTMF signals is more easy. Also DTMF (dual-tone multi-frequency) is normally used to send data to automated phone central kind of system, not from user to another user. As you will find out, it's not so easy to do.

    Web browser supports sending DTMF, btw.. That's where I met those.

    Cheers,

    Hi,

    Well, what you could do it scan for keypresses when the a voice call is in progress, you can know from the sysagent module if the call was in progress or not.

    Hope that helps,

    hi freaky_911
    i have another idea to you what you can do is scan the keys and upload it to a server in a proper sequence and then you can detect that i hope this will help you a bit.
    give a feedback to this idea and really the idea is great
