Parameters hwndOwner A handle to a window to which the configuration dialog box (displayed by TSPI_providerConfig) is attached. This parameter can equal NULL to indicate that any window that is created during the function should have no owner window. dwPermanentProviderID The permanent provider identifier of the service provider to be configured. Return Values Returns zero if the request succeeds or a negative number if an error occurs. Possible return values follow: • LINEERR_INIFILECORRUPT • LINEERR_NOMEM • LINEERR_INVALPARAM • LINEERR_OPERATIONFAILED lineDeallocateCall The lineDeallocateCall function deallocates the specified call handle. Function Details LONG lineDeallocateCall( HCALL hCall ); Parameter hCall The call handle to be deallocated. An application with monitoring privileges for a call can always deallocate its handle for that call. An application with owner privilege for a call can deallocate its handle unless it is the sole owner of the call and the call is not in the idle state. The call handle is invalid after it is deallocated. lineDevSpecific The lineDevSpecific function enables service providers to provide access to features that other TAPI functions do not offer. The extensions are device-specific and the applications must be able to read the extensions to take advantage of these extensions. When used with the Cisco Unified TSP, lineDevSpecific can be used to: • Enable the message waiting lamp for a particular line. • Handle the audio stream (instead of using the provided Cisco wave driver). • Turn On or Off the reporting of media streaming messages for a particular line. • Register a CTI port or route point for dynamic media termination.
