I have a problem to detect voice mail. A telecommunication provider not have the initial message after call connect to voice mail. Every call are redirect to agent. How to configure Call classifier to drop silent call??

Thanks

Can you give some more information:

How are you making the call?

What messages do you see?

What messages do you expect?

Martin,
The response for your questions are below.

How are you making the call? I am using TSAPI cstaMakePredictiveCall to make de call.

What messages do you see? After call connection there is no message. The voice mail start the record just after connect the call.

What messages do you expect? That´s the problem. The Call Classifier expect a message, but hear just silence (the voice mail expecting the message) .

Thanks for your help.

cstaMakePredictiveCall() is described in "TSAPI for Avaya Communication Manager Programmer’s Reference".

Assuming you want the call to be dropped once an answering machine is detected, you should set answerTreat = AT_DROP in the private data of cstaMakePredictiveCall().

If a client application wants to receive events for answering machine detection, the client application should establish a call monitor using cstaMonitorCall() after the application receives a confirmation for the cstaMakePredictiveCall() request.
