TAPI application

[Jim]

I want to build an IVR application, and I am thinking I
might as well use C# to do this. For the moment, this is
a prototype application, so I am not working with any
specialty API's like the ones that Intel provides for the
Dialogic cards. I am just wanting to do this with my good
ol' PC's modem and a straightforward, albeit functional
program I can write.

My modem supports voice-mail type applications, as it acme
with one, so I know it has the capability to process
incomign and outgoing audio, as well as interpret DTMF
tones. I understand there is support for automating this
within the Windows API. Can anyone point me in the right
direction as to where to get started?

I would be content to just get an app up for the moment
that would respond to a ring, or some event that I
generate (like a menu choice / keypress) and answer the
phone, then play a .WAV file "Hello, thank you for
calling......" and then process a DTMF tone, and start
another .WAV file "Choice 1...", "Choice 2..." "Choice
3.... record your message..." and, if appropriate, then
begin recording from the audio input on the modem. What is
basiaclly involved in this? I'm assuming the Windows TAPI
interface supports this kind of stuff, and if so, what do
I need to be doing to get this going? Thanks.

Well you could then easily follow Microsoft .NET Speech
SDK for this purpose. Its damn easy and has samples in C#
as well.

Even I work on such applications, but use Intel's API.
