If you are trying to use the CAPI interface with a Diva Media Board and are having problems or getting error messages that relate to an issue with the CAPI driver, then there are number of checks that can be made to resolve the issue:

The Diva CAPI Service is not installed or has been uninstalled

  • Use the Dialogic Diva Configuration Manager and check that the CAPI service is visible, and that you have a binding to the card. 

  • If CAPI is not shown here, go to 'Insert' > 'CAPI', and then create a binding between CAPI and the Diva Board.

There was an error during driver installation

  • Please uninstall and re-install the Dialogic Diva System Release for Windows.

There is another non-Dialogic Diva ISDN card installed in the computer

  • This scenario is not supported by Windows as it can only handle one CAPI-driver installed. 

  • Multiple ISDN cards from different manufacturers will therefore not work in the Windows environment.

NOTE

having an additional Diva Client card (i.e. a passive card) in the same machine will also not work.

  • You can however install a maximum of eight Diva Analog, BRI, 4BRI, PRI, V-2PRI, four Diva V-4PRI, or two V-8PRI Media Boards in one computer.

  • You can mix different types of Diva Media Boards. 

Another non-Dialogic Diva ISDN card was installed in the computer previously and the driver is still present

  • A CAPI driver will not load correctly if there are files or registry entries of another manufacturer's CAPI driver still present on the system. 

  • Make sure you completely uninstall all other CAPI drivers and then re-install the Dialogic Diva System Release for Windows. 

  • Use the Diva CAPICheck utility to search for other CAPI drivers present - see below.
