Function Details LINE_REQUEST hDevice = (DWORD) 0; dwCallbackInstance = (DWORD) hRegistration; dwParam1 = (DWORD) RequestMode; dwParam2 = (DWORD) RequestModeDetail1; dwParam3 = (DWORD) RequestModeDetail2; Parameters hDevice This parameter is not used. dwCallbackInstance The registration instance of the application that is specified on lineRegisterRequestRecipient. dwParam1 The request mode of the newly pending request. This parameter uses the LINEREQUESTMODE_constants. dwParam2 If dwParam1 is set to LINEREQUESTMODE_DROP, dwParam2 contains the hWnd of the application that requests the drop. Otherwise, dwParam2 is not used. dwParam3 If dwParam1 is set to LINEREQUESTMODE_DROP, the low-order word of dwParam3 contains the wRequestID as specified by the application requesting the drop. Otherwise, dwParam3 is not used. TAPI Line Device Structures The following table lists the TAPI line device structures that the Cisco Unified TSP supports. This section lists the possible values for the structure members as set by the TSP, and provides a cross reference to the functions that use them. If the value of a structure member is device, line, or call specific, the system notes the value for each condition.
