Hello Murad,

You need to use System.IO.Ports namespace (.NET FW 2.0).
Start from these two samples of using modems

Hi,

Voice calls suggests that you use TAPI.

There is nothing in the .NET Framework to support TAPI. While it is
possible to implement the functions that you need (and someone may have done
so), it is more practical, IMO, to use a commercially available TAPI add-on.
I suggest that you take a look at http://www.exceletel.com/ or
http://www.tapiex.com for controls designed for this purpose. You might
spend much more money developing and debugging your own implementation, than
by using some off-the-shelf solution.

Realize that only a small percentage of standard modems support the mode
that you need.
