Answer: What is Telephony Server Application Programming Interface mean?

Telephony Server Application Programming Interface was a computer telephony integration standard developed and promoted by Novell and AT&T. It consisted of a number of call control commands for switching calls, voice mail and call logging using NetWare servers. Unlike the competing Telephony Application Programming Interface from Microsoft and Intel, it was a server-based system that did not expect client-side equipment to handle call switching. This was important to AT&T, which sold large telephone switches that Telephony Server Application Programming Interface was intended to work with.
