    My project requirement is to send SMS and audio recorded calls(like automated recorded alerts) on mobiles to users using AVR ATMEGA32.
    As of today I can send SMS and make audio call. My query is for audio recorded call mechanism when user pick up the call initiated from GSM module.
    I can find and track the response signals from microcontroler when call get dialed and when call hang up by user without response but
    I am unable to track response signal from microcontroller when user receives call. I have also referred GSM module reference PDF but nothing has been specifically mentioned over there.
    As I am not getting response signal I am unable to do my rest of functionally for generating audio recorded call (like any answering machine)when user receives call.
    Appreciates if anyone give me some pointers on this.
