I am currently looking for the way to update TAPI compliant application
( caller ID detector ) written for POTS to work with ISDN lines.
I have a voice modem installed on my PC and the application works properly
In addition, I installed FRITZ!Card PnP ISDN adapter of AVM ( www.avm.com )
and two virtual modems on it. The ISDN adapter is not connected to ISDN
As a result, my application stopped work properly with POTS modem. The debug
sessions shows that TAPI does not call to LineCallbackFunc() at all.
Why? Did anybody encounter this problem?
