Hi.
I have a voice modem name "IC+56K External Data Fax Voice Modem Pnp".

I using TAPI 2.0 to write an application to dial out and generate wave file to information to customers as well as get inbound call and record message from customer.

When i make an dial out to number 11 (i use PBX: Private Branche Exchange), i meet a problem as follow:
The phone number 11 still not pickup yet (callee not pickup yet), but in my application it get the message the line is connected. So it do generate wave file to the line while it is not connected in real.

I don't know why, i use Windows XP.
But inbound call is OK, i can detected digit, answer incoming call, as well as record message from caller.

Have any way to solve this problem
