3.1.6  
Call Forwarding (CF) 
 

Definition  
Call forwarding (CF) enables users to forward all incoming calls (including speaker calls) to another destination. Call forwarding is based on the station number, regardless of how the call reached the activating telephone. If trunk keys have been configured, users can also activate CF individually for a specific trunk key. The following destinations are possible:
 •   Another subscriber station
 •   The attendant console
 •   An external destination
 •   A voice messaging system
 •   Hunt group
 •   ACD groups (such as Hicom Agentline Office)/UCD groups
The user is notified when call forwarding is activated. Notification can be in the form of a special dial tone, an indication on the display, or an LED signal.
Outgoing calls can still be made when call forwarding is activated.
End users can choose to forward only external calls or only internal calls. One single access code is used to deactivate any of these choices.
The following are the default feature access codes:
 •   Call forward both internal and external calls: *11
 •   Call forward external calls only: *12
 •   Call forward internal calls only: *13
 •   Call forwarding off: #1
Call forwarding is implemented on a station number basis, regardless of how the call reached the activating telephone. If trunk keys have been configured, CF can also be activated individually for a specific trunk key.
External Destination
The call forward destination can be an external party. Instead of entering an internal station number, enter the trunk access code, followed by the external number. Since it is possible that an incoming external call could be forwarded to an external destination, the system will check whether the combination of trunks can guarantee release supervision (See table below). If not, a timer is started Time up to warning tone for MSI - transit and default is 300 seconds. Once this timer is up, both subscribers hear a warning tone and another timer is started. Once the second timer is up - Time between warning tone and release, default value: 10 seconds - the trunks are released.
CorNet
Calls can be forwarded over a CorNet link.
If a call is forwarded to another node, and it in turn is forwarded back to the originating node, the CorNet links will be released if the function Rerouting is activated.
Incoming Caller ID (PRI, BRI) is passed from one destination to another within the same system. It is not transferred over CorNet-N to a remote node. If a voice mail system is located in a remote node and the call is forwarded, the voice mail system will receive the station number of the original called party (for version 4.0 even A and B extensions are displayed for call forwarding network-wide).

Dependencies/Restrictions  

 Subject  
 Dependency/Restriction  
Analog telephones  
When using analog telephones, S0 telephones (not for U.S.), and CMI telephones (not for U.S.), you must wait for a confirmation tone after entering external destinations.  
Do not disturb (DND)  
You cannot program CF on a telephone where DND is active.  
Call forwarding  
Up to five call forwarding procedures can be chained.  
External call forwarding  
Regardless of the telephone, one or more keys can be programmed with external CF.  
MSN trunk forwarding  
In V1.0 and later, any user who has an assigned MSN for direct inward dialing can forward this number to the trunk (the feature must be requested from the carrier).  
External call forwarding  
When dialing external destinations, users must prefix the destination number with the CO trunk group code.  
External call forwarding  
User to User Signaling UUS can be deactivated using the flag "Deactivate UUS per direction" (routing parameters). One effect is that the transmission of the A party's calling number is suppressed for external call forwarding in a User-to-User-Info-Element.  
CF destination is an ACD/UCD group  
A call is not forwarded to an ACD/UCD group in the following cases:  
 •   A station is a member of a hunt group. If the hunt group is called and a station with CF to an ACD/UCD group is next in line, the call is not forwarded; instead, the next station in the hunt group is called directly.
 •   A station is a member of a group call. If the group is called, the call is not forwarded to the ACD/UCD group.
 •   A station is a member of a group call no answer. If the group is called, the call is not forwarded to the ACD/UCD group. Exception: The first station entered has activated CF to the ACD/UCD group. In this case, the call is forwarded.
OpenStage telephones  
In the case of systems equipped with simplified dialing (Prime Line), the function key preset for call forwarding on OpenStage stations cannot be programmed with an internal forward destination.  
As a result of the simplified dialing, the system interprets this as forwarding to the exchange. For call forwarding to an internal forward destination, a freely-programmable touch/sensor key should be used.  
Prime Line  
If simplified dialing (Prime Line) is active, you must press the extension key before dialing an internal station number. In this case, you need not enter the trunk group code for external destinations.  
Appointment, automatic wake-up system  
When an appointment comes due, the reminder does not follow call forwarding.
