How to develop an IVRS application using Tapi in C#.
is anyone have any sample code for this.
pls help me.I need it immediately.
You haven't really provided a question that people can respond to in
any meaningful way here (although I will try) . You haven't said what
the App must do or what the telephony equipment is etc.
Tapi is a technology that is quite difficult to get your head around
for anything more complex than a dialling app. The actual
implementation is done by the equipment provider themselves and
although the spec is quite specific, there are usually quite a few
provider quirks to come to grips with.
Now, with an IVR application it is likely I guess that you are either
going to be speaking to a PABX switch or a dialogic card, if this is
the case then I think that you are going to have trouble using c#
unless you are happy to do a *lot* of Pinvoking, in which case you may
be better off using c++ (as the headers are already done for you) The
reason for this is that by far and away the majority of Tapi providers
for switches and dialogic cards are Version 2.2 (unfortunately Tapi 3,
the com version is not widely used) , and the issue you will have is
that the spec requires that you set up structs inside variable length
buffers, and the struct will get populated with offsets into the
buffer, not a trivial thing to do in c# or .NET generally, but fairly
straight forward to do in C++ (or Delphi).
Another option that you may have, is that a lot of providers also
provide a additional API for their equipment as well as Tapi, often it
is a com interface, you may have much more success with this rather
than Tapi.
Hope that helps.
Cheers Tim.
