This message is sent to an application to report the results of function call that completed asynchronously.
Syntax

dwParam2 = (DWORD) Status;
dwParam3 = (DWORD) 0;

- hPhone
Not used by this message. Value is NULL.
- dwCallbackInstance
Value that returns the application's callback instance.
- dwParam1
Request identifier for which this is the reply.
- dwParam2
Success or error indication. The application should cast this parameter into a LONG. Zero indicates success; a negative number indicates an error.

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.
