Hi, I was just wondering how I would implement a phone responder. You know those things that pick up and ask you a question and then ask you to press a number (1 for yes, 2 for no, # to repeat), or enter a number and so forth! If you know what i'm talking about, would you know how to implement one in VB or is it impossible? I'd like to mess around with that before I start learning C++. Because i'm getting kinda bored :S!
Look up TAPI
I see I see. Thanx for your response..but I would like to know how to use them. Such as interpret certain frequencies of different numbers! Thank you very much though. atleast I have an idea of what to look at. Aight, i g2g search them now, peace!
what is the hardware that you want to use? is it one of those (old?) voice-fax-modems? most of the stuff like this is driven by standard AT comands, but you need a list of them from your modem's manual or something. TAPI is useful, but in my opinion extremely complicated for basic functions like you described.
interpreting frequencies and stuff is done by a DSP chip inside that machine, you should normally set it in DTMF listen mode somehow (AT commands again) and it will report the strings of DTMFs received over your serial connection.
if you get serious about this, feel fre to ask, i kinda have a lot of experience in telecom and voice apps... (i wish i could get back there again, i havent touched that for the last few months, hehehe). never did that on voice modems though, there are specialized boards for that.
