yes that's correct i am still trying to connect 8051+ISD+Any dialer chip to send a message, so as i am in the beginning stage, i decided to first work with any one chip telephone IC and see it working with telephone. later once i gone through the procedure i will then try to connect it with 8051. any way at the moment just one chip IC and using it as a completer telephone system. i will be going through the documentation and try to make sense of it, i don't have much analog experience so obviously my preference will be to work with any schematic. so at the moment i am search for any basic working schematic on the net.


being specific can you describe me in little how can i dial a number, i have seen chips with keyboard interfaces like UBA2051, so i think i can control these pins through microcontroller to dial a number, but in a chip like TEA1062 there is no such keyboard interface, so my first specific concern is how to dial a number through this chip.

sorry i am very very backward in these as its only 3 days i am venturnig in this teritory so i need some basic education.
