Return Values
-
On completion of ClientRequest, this field MUST contain the result of the encapsulated telephony request. A nonzero request ID value indicates that the request is in progress and will complete asynchronously, and a LINEERR_Constants value indicates synchronous failure.
-
Returns a positive request identifier if the asynchronous operation starts; otherwise, the function returns one of these negative error values:
