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.
