Design a GSM Modem with Audio Feature

I want to have a GSM modem based on SIM 900A with voice calling and recieving option. It need to have a serial interface through which i can use AT commands as offered by the modem also. For voice I can attach a microphone and speaker. It should give some interface when call is coming and for making calls a simple button/switch can be used which will dial to a predefined number , so no need for keypad.
