Read serial from phone keypad

I am writing a software that will get serial numbers from users and then validate it and finally give a number back to the users.

I want to use a voice dial up modem to answer the users and get the serial by pressing the phone numbers using tone pulses.

I am doing this in C#. It works on the website but I don't know how to read serial from the modem.

You need to look at TAPI - Telephony API. It includes things like reading DTMF tones from a suitable modem. Google TAPI 3 (if you're using C#) or TAPI 2 for C/C++.
