Hi,
im trying to do a project where it requires auto dialing, i.e. to dial a specific number when triggered to do so.
well, my teacher suggested i recorde the number (sound of numbers) i want to dial on a record/playback chip and play it when its time to call, but i dont know where to play it??
my question is: i know that each number has a diff. frecuency, but how does the sound get through? is it through the DTMF? and if so, can i just play a pre-recorded dialed numbers and that would work??
the phone i took apart has this IC UTC2411, and i searched the net for a data sheet, but all i got is wholesale lists for that IC.. anyone knows a good online source for IC's data sheets ? or any other source?
i thought that this should be easy, but it isnt as easy as i thought. please help!!
thank you
