Hi,
<br>
<br> I have writtena a code which makes calls using Intel Dialogic card. It has a T1 interface through which it makes calls.
<br>
<br> My code works fine. it dials and plays the wave file. the problem I have is my code doesnt wait for the operator Intercept (doesnt wait for the response from the other end, plays file when the other end goes off hook).
<br>
<br> researching the web I found that I should use ATDX_CPTERM() function to enable call analysis. but the problem is my code doesnt send a signal to ATDX_CPTERM(). I dont know where I am going wrong. please correct me.
