-------------------------------------------------------------------------- Copyright (C) 1998-1999 Microsoft Corporation. All rights reserved. -------------------------------------------------------------------------- TAPI 3.0 T3IN Sample Application Overview: ~~~~~~~~~ T3IN is a sample TAPI 3.0 application that waits for and answers incoming phone calls. In order to receive incoming call notifications, as well as any call state event notifications, the outgoing ITCallNotification interface must be implemented by the TAPI 3.0 application, and registered with TAPI 3.0 through the IConnectionPoint mechanism. For more information on IConnectionPoint, and IConnectiontPointContainer, please refer to the COM documentation. CALLNOT.CPP and CALLNOT.H show the implementation of the ITCallNotification interface. ITCallNotification is defined by TAPI 3.0, and the interface definition is in tapi3.h. INCOMING.CPP shows how to register the interface, and how to answer an incoming call. How to build the sample: ~~~~~~~~~~~~~~~~~~~~~~~~ To run the T3IN sample application, set the SDK build environment, then type "nmake" in the incoming directory. This will build T3IN.EXE. How to use the sample: ~~~~~~~~~~~~~~~~~~~~~~ After the sample is built, run T3IN.EXE. A small dialog box will appear, and the status will be "Waiting for a call." If your computer does not have any TAPI devices, the application will display an error as is starts up. The application will wait for calls on all TAPI addresses that support audio calls. If a call comes in that has both audio and video, the sample will also set up the video streams. When a call arrives on one of the TAPI addresses, the "Answer" button will be enabled, and the status message will change to "Click the Answer button". When the "Answer" button is clicked, the application will answer the call. Alternatively, there is an auto-answer box that, when checked, will make the application proceed as soon as a call is received. What functionality does this sample show: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The incoming sample application demonstrates how to receive new call notification and call state event notifications. It also demonstrates the basic TAPI 3.0 functions involved in answering a call. What this sample does not show: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ This sample does not let the user choose the TAPI address for the application to use. It does not allow the user to decide what media types to listen for, and it does not allow the user to decide what terminals to use. Hints: ~~~~~~ This sample should be able to run as long as you have TAPI devices installed. Many computers have a modem. If the modem is installed correctly, it will show up as a TAPI device. Also, there are TAPI devices corresponding to various IP telephony services that are present on most systems.
