Short for Telephony Server API, an API developed by Novell and AT&T that enables programmers to build telephony and CTI applications. TSAPI is similar to TAPI, which was developed by Microsoft and Intel. But whereas TAPI has been implemented for the Windows operating system, TSAPI runs on Netware platforms. Another key difference is that TAPI can be used for both client – and server -based applications whereas TSAPI is strictly a server API.
