10.14.2.3.4. Directed Call Park Feature Invocation from ACWin (MQ) 
The Attendant needs to be connected to the call in order to invoke
the feature.
The Attendant then enters the consultation state by pressing the consultation
key and dials the feature code. Note. Only invocation from feature code
is possible.
The Attendant keys the directory number of the terminal to which the
call is to be parked.
The display information presented to the Attendant is <FC><DN>
in the status field.
If the call is successfully parked, then the attendant will receive
the message 'PARKED', the call is released from the Attendant
and the loop key becomes free.
If the call is not successfully parked, then the attendant will receive
the message
'NOT POSSIBLE', and the call will remain on hold.
in the OpenScape 4000 it is not possible for the Attendant to Retrieve
the parked call, since the OpenScape 4000 Retrieve solution is not based
upon Pickup. The attendant will be able to 'reconnect' to parked
calls by invoking the feature Directed Call Pickup.
Parked Calls Recalled to Attendant
When a parked call is recalled to the attendant, for whatever reason,
then it will be presented to the source button assigned for recall and
queued if necessary.
To connect to the recalled party, the Attendant clicks on the recall
source button or presses the recall source key on the P.C. keyboard
