I'm working on a project based on IVR(Interactive Voice Response). In which registration, modification in DB will take place by dialing a telephone no. and following simple steps, like that, which is used in telecom help centers to change our tariff or sms packages etc.

Can I use simple voice modem with c# code with TAPI at back-end to mange all this?
Actually, I have "conexant hda d330 mdc v.92 modem". Can I use this to make this type of application...?

If yes, can we handle more than one call on this modem?

If not, what hardware will be required to perform this?

Thanks in advance.

You clearly cannot handle more than one call, on a single modem. You only have one phone line, and even if it has call waiting, no real way to work with it. It sounds to me like you've accepted a project and have no idea how to do it. I promise this is too complex for you to do, if you have no clue at the outset how it is done.
