How to gather digits pressed from the numpad of phone to the host computer ?
I wann to develop following project,
Our computer is connected to a telephone line with modem.
The respective student will call to our computer via telephone.
The computer will receive the phone and play one wave file in the handset
asking the student for his exam seat no. The student will then provide his
exam seat no. by pressing buttons on his numerical pad of telephone.
Then the computer will recognise that no and retrives that no in database.
and tell the result of the student.
Sir please provide me guideline regarding my project.
