  There is sample TAPI delphi code at:

  http://www.delphimag.com/features/1999/11/di199911re_f/di199911re_d.asp

  It demonstrates the use of "callbacks" in delphi, which appears to be
  your main problem.

  Unfortunately that code is written for D4 and makes extensive use of
  DWORD, so you will not be able to use it without modification.

  Just to point you a bit;

    the main callback routine there is:  LineCallBack(...)


Which is defined as follows (in that code):

  ErrNo := LineInitialize(
           @rTapi.hTapi,        // Usage Handle (other TAPI functions need).
           MainInstance,        // TAPI.DLL stores info here (can forget).
           rTapi.pLineCallback, // Function windows will call with msgs.
           '',                  // Optional app name. (for LINECALLINFO).
           @rTapi.dwNumDevs);   // # of devices(modems/virtual) returned here.

  rTapi.pLineCallback is a pointer to the LineCallBack(...) function.


  I will not be able to give you much additional help, since that
  program was my first and last effort with both DELPHI and TAPI.


  Good Luck;
