Telephony Application Programming Interface Version 3.1
The Microsoft Telephony Application Programming Interface (TAPI) version 3.1 is a Component Object Model (COM)-based API that merges classic and IP telephony.
Possible TAPI applications include:
- Multicast multimedia IP conferencing with quality of service (QOS)
- Voice calls over the Internet using the H.323 protocol
- Call center applications capable of tracking multiple agents
- Basic voice calls on the Public Switched Telephone Network (PSTN)
- PBX control
- Interactive voice response (IVR) systems
- Voice mail
You can write TAPI-enabled applications in many languages, including Java, Visual Basic, and C/C++. Familiarity with COM is required. Development experience with telecommunications or other telephony applications is helpful, but not necessary.
TAPI version 3.1 enables development of communications applications for Windows Server 2003 operating systems, Windows XP, and Windows 2000.
