I have a WinCE 3.0 application that uses the TAPI interface, and have successfully established communication from that application to a remote PC. The application also needs to be able to disconnect the phone when the user is through with data transfer. I am attempting to disconnect by using the following TAPI functions:

::lineDrop();
::lineDeallocateCall();
hCall = NULL;
lineClose();
hLine = NULL;
::lineShutdown();

All functions (appear to) execute successfully, but i have not been able to disconnect the phone. I am using a Nokia 3285 AT.

Have you any suggestions? Thank you
