Syntax
HRESULT ParkDirect(
[in] BSTR pParkAddress
);
Parameters
[in] pParkAddress
Pointer to BSTR containing the address where the call is to be parked.
Return value
This method can return one of these values.
| Return code | Description |
|---|---|
|
Method succeeded. |
|
The pParkAddress parameter is not a valid pointer. |
|
Park is not supported. |
|
The pParkAddress parameter is not valid. |
|
Insufficient memory exists to perform the operation. |
|
The operation failed because the TAPI 3 DLL timed it out. The timeout interval is two minutes. |
Remarks
Some service providers do not support this operation while streaming is active. The application may need to call ITStream::StopStream or ITSubStream::StopSubStream prior to the operation and ITStream::StartStream or ITSubStream::StartSubStream following completion of the operation.
With directed park, the application determines the address at which it wants to park the call. With ParkInDirect, the switch determines the address and provides this to the application. In either case, a parked call can be unparked by specifying this address.
The parked call enters the disconnected state after it has been successfully parked.
Some switches can remind the user after a call has been parked for some long amount of time. The application sees an offering call with a call reason set to reminder.
The application must use SysAllocString to allocate memory for the pParkAddress parameter and use SysFreeString to free the memory when the variable is no longer needed.
