The lineSwapHold function swaps the specified active call with the specified call on consultation hold.
Handle to the active call. The application must be an owner of the call. The call state of hActiveCall must be connected.
Handle to the consultation call. The application must be an owner of the call. The call state of hHeldCall can be onHoldPendingTransfer, onHoldPendingConference, or onHold.
Returns a positive request identifier if the function is completed asynchronously, or a negative error number if an error occurs. The dwParam2 parameter of the corresponding LINE_REPLY message is zero if the function succeeds or it is a negative error number if an error occurs. Possible return values are:
LINEERR_INVALCALLHANDLE, LINEERR_OPERATIONUNAVAIL, LINEERR_INVALCALLSTATE, LINEERR_OPERATIONFAILED, LINEERR_NOMEM, LINEERR_RESOURCEUNAVAIL, LINEERR_NOTOWNER, LINEERR_UNINITIALIZED.
Swapping the active call with the call on consultation hold allows the application to alternate or toggle between these two calls. This is typical in call waiting.
