Automatic Callback When Free or Busy 
 

Definition  
Users can activate an automatic callback to a free or busy internal station. When the callback destination finishes its call (when busy) or initiates an outgoing call, the system calls back. First, the system calls the user who initiated the call. After that user answers, the system calls back the station the initiating user wishes to speak with.
A telephone can initiate up to five callback requests and be the destination for up to five requests. Further requests beyond these limits are rejected.
Callback requests are deleted when:
 •   the call is completed
 •   the initiator cancels the request
 •   every day at 11:57 p.m. the system deletes all callbacks that were initiated towards other CorNet nodes
Callback requests can be set on internal stations and groups, but not on groups located in other CorNet nodes.

HiPath 4000/3000 Networking (CorNet-NQ)  
In a HiPath 4000 to HiPath 3000 connection, the call completion request will be signaled depending on the type of telephone (callback signaling). At the receiving end, display telephones show call back information (Missed Calls List) after the MWI (Mailbox) key is pressed.
Callback Requests Set on a Group
 •   A request set on a hunt group is set on the first member of the group.
 •   A request set on a Group Call is set on the first member of the group.

 Callback  
The callback is not deleted until the call is completed or the initiating station deletes the callback.  
Every night at 11:57 p.m., all callbacks that are not within the system (CorNet) are deleted.  
A callback can be set to an internal group (not DSS1, CorNet-N, or QSig). The callback is stored with the first station in the group.
