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.

Hello, We can make a interface using c#. Windows provide a "Serial Port" component where we give the port of arduino or microcontroller which you are using to control the GSM model. I have done this type of work. I can help you in this project. So let me know if you are interested. Thank You

Hey, I've worked with sim 900 modules before, in fact I have one on my desk right now. From what I can tell you need kind of a stripped down phone.. I can see it being helpful as a senior citizen friendly phone, something for emergencies.. Let's discuss what you need exactly. I'm free this weekend so I might be able to do this by Monday even.
