Installation and testing of a TAPI driver
On this page

Installing a TAPI driver

  • The installation of a TAPI driver is to be made by the manufacturer's instructions. Normally a installation routine should be provided.
    Hints:
    • On 64-bit systems, a 64-bit TAPI driver must be installed.
    • The installation of a TAPI driver requires administrator privileges.
    • A TAPI driver can be installed only once on a Windows system. A per-user installation is not possible.
    • Some TAPI driver may only be installed on one computer (for example, the Auerswald LAN-TAPI). In this case, the xtelsio CTI Servers distribute the TAPI lines of the driver to multiple CTI Clients on the network.
  • If no TAPI lines are available after installation of a TAPI driver, then try to restart the computer.
  • Under [Control Panel > Phone and Modem Options > Advanced] all installed drivers are listed.
  • A TAPI driver can provide one or more TAPI lines (TAPI devices) in the system.

How-to test a TAPI driver

  1. For testing you can use the phone.exe TAPI tool.
    http://www.itecsoft.de/download/phone.zip
  2. Extract the ZIP archive.
  3. Run phone.exe.
  4. In the choice field "Device" all available TAPI lines are visible.
    1. If none of the expected TAPI lines are available, please follow the instructions under "The TAPI driver no longer works - what you can do".
  5. Select your TAPI line.
  6. Click o [Start Session] to open the line.
    1. If successfull, the button should switch to [End Session] and the [Configure] button is enabled.
    2. If the line could not be opened, an error message is given in the lower status line, e.g. "(0x80000048) Operation Failed". This can have different causes:
      • The TAPI driver or the telephony hardware is not configured properly.
      • The communication with the telephony hardware is disturbed (serial interface, USB, LAN - according to driver).
  7. Test lineMakeCall:
    1. Enter a phone number in the field "phone #" . The button [Make Call] should be enabled now. When the button keeps disabled, there is still a problem with the TAPI line. This can occur with an Auerswald LAN-TAPI, for example, if the extension is not entered in the PBX under [Functions > LAN-TAPI].
    2. Click [Make Call]. If first your phone rings, please offhook the receiver. Now your telephone should call the destination number.
    3. Within the frame "Calls" information about the current connection should be signalised.
    4. If nothing happens, a error should be given in the status line.
    5. You can finish the call with the button [Hang Up].
  8. Test incoming calls:
    1. Call your telephone with you mobile.
    2. Within the frame "Calls" information about the incoming call should be signalised.
    3. If your TAPI drivers supports lineAswer, the button [Answer] should be enabled.
  9. Test line configuration:
    1. Click the button [Configure].
      Now the TAPI driver's line configuration dialog should be displayed.
      If no dialog appears, the following reasons are possible:
      • The driver has no line configuration.
      • The TAPI driver is 64 bit and the application is 32 bit.
      • The TAPI driver has a problem.
    2. Alternatively, you get into the driver configuration via [Control Panel > Phone and Modem Options > Advanced > Configure...].

The TAPI driver does not work - what can you do?

  1. Please check if the TAPI driver is visible under [System Control > Phone and Modem Options > Advanced].
    => If the driver is not to visible, please install it again.
  2. Check the connection between TAPI driver and phone hardware; (serial interface, USB cable, LAN - according to driver).
  3. Check the driver configuration via [System Control > Phone and Modem Options > Advanced > Configure...].
  4. Re-boot your computer.
  5. Restart, perhaps, your PBX. Ask in the case of doubt your administrator.
  6. Restart your phone (may remove the cable and connect it again).
  7. Check the line configuration with phone.exe - see point QT006 9.

TAPI configuration is changed after restarting Windows

  • In Windows 10 in connection with an Auerswald LAN TAPI the case occurred that after a Windows restart the TAPI configuration was changed. An incorrect TAPI line was bound to the PhoneDialog in the CTI Client.
  • The following could help:
    • Under [Control Panel > Hardware and Sound > Power Options > System Settings > Shutdown Settings]: Here you could test "deactivate the quick start".
