About the Telephony Service Provider (TSP)

[ The H323 and IPConf TSPs are not available for use in Windows Vista, Windows Server 2008, and subsequent versions of the operating system. The RTC Client API provides similar functionality.]

A TAPI telephony service provider (TSP) is a dynamic-link library (DLL) that supports communications device control through a set of exported service functions.

For detailed information, please see the Resource Kit for the target operating system. Third-party TSPs for specialized communications devices will typically be provided by the manufacturer and will be installed with the device.

The following topics describe how to create a TSP that will function properly within the Microsoft Telephony environment, and how to create a TSP/MSP pair:

Note  A TSP is a user-created DLL. If you are creating a TSP for a 64-bit Windows platform, you must compile it as a 64-bit DLL or DLLs.
