Microsoft TAPI (Telephony API) in Windows provides telephony functionality for the application, it is a bit confusing for programmers. I have many friends asking me the same question how to connect and communicate through modem. Finally, I came up with this sample tool to do the coaching. I tried to keep this tool source bare minimum to get an easy hold of TAPI programming even though I got to do some juggling. Here, I have used TAPI 2.0. TAPI 3.0 and above is much more simplified and easy to use.
