Telephony Application Programming Interface (TAPI) is a programming interface for CTI (computer telephony integration) applications.
Applications using TAPI need a TAPI driver (also referred to as TSP). This TAPI driver has to be delivered by the phone manufacturer. As this driver is always device-dependent, it is not possible to use a generic driver which is supplied with the operating system. The driver often has the name of the manufacturer or the phone system, sometimes in combination with the extension number.
To check whether a TAPI driver is installed, do the following (Instructions for Windows XP).
• | Start, Control Panel |
• | Phone and Modem options |
• | TAB advanced |
There are a lot of drivers which come with Windows like NDIS Proxy TAPI Service Provider. Search for a driver with the name of the PBX, PBX vendor or your direct line. If this driver is missing, you probably do not have the correct TAPI driver for your PBX.
If your TAPI driver is not listed here see: I cannot select my TAPI driver in the configuration wizard
