4. Drivers and Applications
Some standard CAPI applications are:
Online services
Online services should be configured to use the CAPI wherever possible, as this offers you the fastest and safest service access.
Fax (analog and digital)
ISDN application program suites usually use the CAPI for all services, including analog (Group 3) and digital (Group 4) fax. Analog faxing requires a softfax module, which is a component of the ISDN driver. This driver should be used instead of any softfax module offered by the application, since it uses the PC’s resources more economically.
Euro File Transfer
Euro File Transfer (EFT) was developed for the simple exchange of files via ISDN. It replaces the X/Y/Zmodem protocols. You can call any EFT server the way you call a BBS and upload or download files.
Voicemail
CAPI programs are able to preserve B channel data without any modification. These data may include digital speech from a telephone call. It is immaterial whether the call originates from within the analog phone network or from an ISDN line. Voicemail programs play back announcements to callers and record messages.
The CAPI interface is able to handle ISDN Adapter with different properties. If you wish to use a specific application, you need to make sure that the ISDN Adapter meets the application’s requirements. Some applications may need special B channel protocols, hardware phone connections, or similar.
The technical specifications for your ISDN Adapter are found in the Appendix.
Only one CAPI can be installed at any time, because the CAPI2032.DLL file must be located in a specific directory and each directory can only contain one file by the same name. This means that if you previously installed a CAPI device on your PC, you will have to deinstall it first before you can install the CAPI of the new ISDN adapter. If you fail to do so, the old files will be overwritten, which may result in system crashes and misconfigurations in certain cases.
Make sure to remove all previous CAPI installations before installing this device.
