Yes, U can do IVR system by TAPI Programming.

WAY 1:=
-------
The H/W needed is a Tele Modem. , and Land line connection.

WAY 2:=
--------
U can use GSM-Modem, In that case U do not need TAPI. U will do Serial Port (RS232) Programming or USB - Port Prog. Based upon GSM-Modem type ( either Serial Port or USB port).
In this case u can use mobile SIM in this Modem and It will communicate with Mob. Tower.
U do not need Landline connectivity.

WAY 3:=
--------
This way I preffer. Develop a small device using DTMF decoder ( MT8870) & Microcontroller ( 89C51) & Tri-state Buffer I.C. (MAX232) and any Mobile phone.
The Embedded Prog. can be written at Embedded C. This Device will send Caller ID, and the Mob-Switch pressed to your PC , through Serial Port. ( or u can use USB port chip also)
Then your C# or VC++ or JAVA program will read the caller ID & key pressed detail & then will take any action , such as read database & speak to caller.

If U are not Expert in microcontroller , then U follow WAY 1 or WAY 2. else u can collect such dev. from others.
