I have been able to create an application that (ab)uses TAPI3Lib and understands incoming calls, puts them on hold, rings an internal number, connects the line that is on hold with the target number.

Below is the code getting the caller number

Hello fellow programmers

I'm writing a program to C # which manages TAPI library. I will not give the code (unless someone requests it) because it has commands for a software called Softone and is business related. The problem I'm facing is the following:

I want for example when a call comes to perform a function. Quite simple. So I set the event hanlder and call the function but while it is running the result it gives to the program I mentioned (Softone) is wrong. The same function whether executed manually or in any other way gives correct results. I tried to disable the event handler, execute the function, and re-activate the event handler. But this is also a failure.

What I would like is another way to prevent events from falsifying the data of he function. Do you have anything to suggest?

I'm a beginner so please show understanding. Thanks :)
