TForm1.Button1Click(Sender: TObject);

  try
    hbTapiLine1.CallParams.MediaMode := LINEMEDIAMODE_INTERACTIVEVOICE; // interactive voice call
    hbTapiLine1.MakeCall(Edit1.Text); // phone number
  except
    on EhbTapiError do
      MessageDlg('MakeCall failed!' + E.Message, mtInformation, [mbOk], 0);
