Introduction to TAPI and Basic Setup.

TAPI (Telephony Application Program Interface) is a standard program interface that lets you and your computer "talk" over telephones or video phones to people or phone-connected resources elsewhere in the world. Assuming your computer is equipped with TAPI and your setup includes the right application and hardware, you may be able:

• Call someone by clicking on their picture or other image
• Use a similar graphical user interface (GUI) to set up a conference call and then attend the call at the scheduled time
• See who you're talking to individually or at a conference call
• Add a voice note to an e-mail note you send or listen to a voice note attached to an e-mail note you receive
• Program your computer to automatically receive phone calls from certain numbers (but not from others)
• Send and receive faxes
• Do these things from a portable wireless/cellular telephone/computer as well as from a desktop computer

BASIC TAPI APPLICATIONS :

Microsoft has defined some basic APIs which can be invoked/supported from application code. All Microsoft defined APIsthat can be used from the TAPI applications are declared in TAPI.H file. TAPI.H file is a standard library file that is with the VC++/VS2005 Installation. For example, C:\Program Files\Microsoft Visual Studio\VC98\Include\TAPI.H. To use any specific API which is added or provided by Cisco TSP, the application needs to invoke that API by using the LineDevSpecific API.

Cisco TSP Components :

The following are Cisco TSP components:

• CiscoTSP dll– TAPI service implementation provided by Cisco TSP
• CTIQBE over TCP/IP – Cisco protocol used to monitor and control devices and lines
• CTI Manager Service – Manages CTI resources and connections to devices. Exposed to 3rd-party
applications via Cisco TSP and/or JTAPI API
