This code sample is named HelloTAPI. It demonstrates how to write a simple TAPI phone-dialing application.
Navigate to the solution file (*.sln), and double-click it. By default, the solution files are copied to the following folders:
C:\Program Files\Windows Mobile 6 SDK\Samples\Common\CPP\Win32\CellCore\TAPI\HelloTAPI
Microsoft Visual Studio 2005 launches and loads the solution.
Build the solution (Ctrl+Shift+B).
Deploy the solution (F5).
A dialog box is presented allowing you to key-in a phone number which is then dialed using the TAPI function tapiRequestMakeCall.
