System to handle calls and messages

[theb]

Hi Raspberry Pi experts,

I had the idea to use my Raspberry Pi as some kind of IVR system.

I'd like to connect a SIM card to my RaPi and handle voice calls and messages. It's not necessary to have a conversation with the caller, everything should be done automatically.

Messages (inbound and outbound):
Someone sends a text message to the RaPi number. The text is processed and a message should be returned to the sender.

Voice (inbound only):
Someone calls the RaPi number. An audio file to welcome the caller should be played (e.g. "Hello Mr. X, thanks for calling. Please enter your PIN"). The input should be captured, the PIN validated, and an action triggered (a text message should be sent, e.g. "You've successfully validated your identity").

While I already know that the part with the text messages is not a problem with the RaPi, I could not find any relevant information about the voice part.

Is it possible to implement my idea - and how? Which hardware would you recommend?

Thanks a lot in advance!

Cheers, theb

You should check forums for the PBX software "asterisk" or similar software ( FreePBX, Incredible PBX ).
