The call state of hActiveCall must be connected.
hHeldCall
The handle to the consultation call. The application must be an owner of the
call. The call state of hHeldCall can be onHoldPendingTransfer, onHoldPendingConference, onHold .
Return Values
Returns a positive request ID if the function will be completed
asynchronously, or a negative error number if an error has occurred. The dwParam2 parameter of the corresponding LINE_REPLY message is zero if the function is successful or it is a negative error
number if an error has occurred. Possible return values are:
LINEERR_INVALCALLHANDLE, LINEERR_OPERATIONUNAVAIL, LINEERR_INVALCALLSTATE,
LINEERR_OPERATIONFAILED, LINEERR_NOMEM, LINEERR_RESOURCEUNAVAIL, LINEERR_NOTOWNER,

Remarks
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.
