AVR ATMEGA32 - How to use for automated recorded voice call

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.
