The Telephony Application Programming Interface (TAPI) is a Microsoft Windows API, which provides computer telephony integration and enables PC's running Microsoft Windows to use telephone services. This Interface was developed by Microsoft and Intel in 1993. With Microsoft Windows 95, TAPI was integrated into the operating system. Applications like ISDN (well known in Europe) are using TAPI.

The TSP driver (TSP = TAPI Service Provider) is co-installed on your system during the installation of the client. Subsequently can TAPI compliant software (e.g. Microsoft Outlook) configure and use the TSP driver as telephone line. The actual configuration process differs between manufacturers. Please refer to the manual of your software (e.g. a Customer Relationship Management software) for details about TAPI configuration.

Current TAPI version: TAPI 2.2
The name of our TAPI telephon line is: NCTI standard   

Calls that are routed through the client are signalled by our TSP (Telephony Service Provider) automatically to all other TAPI compliant applications (other third party CRM software). Third party applications can use information that is offered by the phone to open contact windows or notice forms.
