Request Object

The Request Object is created using COM CoCreateInstance and exposes one interface, ITRequest. This interface exposes the MakeCall method, which allows a TAPI 3.0 application to use Assisted Telephony. Assisted Telephony provides telephony-enabled applications with a simple mechanism for making phone calls without requiring the developer to become fully literate in telephony.

For example, a spreadsheet application can add a "Make Call" button using Assisted Telephony without implementing the more elaborate controls available in a full TAPI application.

See the Assisted Telephony Overview for additional information.
