I need a circuit for landline auto dialler which can be easily interfaced with a microcontroller to dial numbers and play voice message. The Voice message input should be in the form of analog input, and the circuit should give a digital signal output when the user on the other end picks up the receiver. The number to dial will be provided by the microcontroller. I need only the circuit part, the microcontroller interafacing and program is not needed.
