Telephony Application Programming Interfaces (TAPI, TSPI, MSPI)

The Microsoft® Windows® operating system Telephony Application Programming Interface (TAPI 3.0) is an evolutionary API providing convergence of both traditional PSTN telephony and IP telephony. IP telephony is an emerging set of technologies that enables voice, data, and video collaboration over existing LANs, WANs, and the Internet. TAPI 3.0 enables IP telephony on Windows 2000 by providing simple and generic methods for making connections between two or more computers and accessing any media streams involved in the connection.
