Hello ,
I hope this is the right forum in the board to post this query.
I would be designing an interactive voice response (IVR) system using the SIM GSM modem.
The system will pick up the phone at the third ring and give a voice message out :
press 1 for this, press 2 for that , etc etc.
When the person presses the appropriate number some action will be taken by the micro board.
The system also should support making voice calls from this equipment when the above situation is not happening.
I need help on two aspects :
1) How to trap the button pressed by the remote user ?Is there any IC which can do this ?
2) How to have a parallel system for both voice conversation and IVR which can be switched as required ?
Does anyone have a reference design which they can point me to.
TIA
Thomas
