The TAPI PHONE_REPLY message is sent to an application to report the results of function call that completed asynchronously.
Parameters

-
dwCallbackInstance
-
Returns the application's callback instance.
-
dwParam1
-
The request identifier for which this is the reply.
-
dwParam2

The success or error indication. The application should cast this parameter into a LONG. Zero indicates success; a negative number indicates an error.
-
dwParam3

Return value
No return value.
Remarks
Functions that operate asynchronously return a positive request identifier value to the application. This request identifier is returned with the reply message to identify the request that was completed. The other parameter for the PHONE_REPLY message carries the success or failure indication. Possible errors are the same as those defined by the corresponding function. This message cannot be disabled.
