Call Forwarding-No Answer (CFNA) With a Timeout 
 
Implementing features, see also Manager E Call Forwarding - No Answer (CFNA) With a Timeout

Definition  
With this feature, calls arriving at a specific destination are forwarded if they are not answered within a specified period.
Call forwarding-no answer in conjunction with direct inward dialing, call allocation, and internal calls is carried out according to station numbers in call management.
Each call signaled at a station is also signaled at stations in the call ringing group; in other words, the call is forwarded to these stations as well.
This type of forwarding is also referred as Fixed call forwarding-no answer in that, once the destination has been set in the database, it cannot be activated/deactivated or changed by the end user. The destination can only be changed by maintenance personnel via Assistant T or HiPath 3000/5000 Manager E. Call Forwarding-no answer in conjunction with Direct inward dialing, Call allocation, and Internal calls is carried out according to station numbers in Call Management. Up to three Call forwarding-no answer destinations can be configured in the Call Management tables for the stations. That is, if the initial station has assigned a ring no answer destination, the incoming call forwards to that assigned destination. If in turn this second destination does not answer, Call Management searches for a further destination to route the call.
Call forwarding-no answer chaining is only possible between destinations in the CM tables. That is, if a destination has Call Forwarding (CF) configured on the telephone, the incoming call forwards to this destination, but will NOT forward to a further destination even if that destination is itself forwarded.
A call forward destination can be a voice mail hunt group.
If the last destination in CM is busy, the incoming call does not progress beyond the ringing telephone until the busy telephone becomes idle. At which time, the call is forwarded to the now idle telephone.
The external and internal call ring cadences are carried over from one destination to the other.
Incoming Caller ID (PRI and BRI) is also carried over from one destination to the next. Except if CF external: then Caller ID is not presented, just the original CF number called (for Version 4.0 even display of A- and B-extensions).
Each call signaled at a station is also signaled at stations in the call ringing group. That is, the calls are forwarded to these stations as well.

CorNet-N  
Calls can be forwarded over a CorNet link.

Call forwarding  
If the call forwarding destination is unavailable and no other call forwarding operation is configured for the trunk, call forwarding-no answer is not carried out.  
Hunting to external call forwarding destination  
The system-wide flag controls the call forwarding - no answer if an external CF has been activated within a call destination list.  
If the flag is not set, the call forwarding - no answer ends at the external CF destination.  
If the flag is set, the call forwarding - no answer continues out of the external CF destination to the station entered in the call destination list.  
Note: For CF on loop start trunks, the flag functions only if you have entered a call cycle for the call forwarding - no answer.  
External call forwarding  
You can specify whether the system follows an external call forwarding procedure that a station has programmed in the call forwarding table.  
External call forwarding  
If you activate external call forwarding for the entire trunk, the system bypasses internal call management (for more information, refer to the ISDN features CFB and CFNR).  
DISA  
This feature cannot be activated/deactivated or changed by anything other than the Assistant T or HiPath 3000 Manager E.  
Call waiting rejection  
A secondary destination which has activated DND, will be skipped.  
Analog telephones  
There is no indication at these telephones that the call being presented is a forwarded call.  
Display telephones  
An incoming call to a forwarded telephone displays the prompt: Call from: xxx. Secondary forwarding destinations will display the prompt: Call from:xxx, where xxx is the original destination dialed by the caller.  
Variable call forwarding definition from the telephone  
Call forwarding can also be configured using the telephone user interface for the local extension. This is possible for all telephone models. External destinations and groups can also be entered.  
Hunting to external call forwarding destination  
The system-wide flag controls the call forwarding - no answer if an external CF has been activated within a call destination list.  
If the flag is not set, the call forwarding - no answer ends at the external CF destination.  
If the flag is set, the call forwarding - no answer continues out of the external CF destination to the station entered in the call destination list.  
Note: For CF on discriminating digit trunks, the flag functions only if you have entered a call cycle for the call forwarding - no answer.  
Multiple call diversion keys for various external destinations  
The telephone user interface allows several different call diversions to be saved to the keys of the DSS module. Several call diversion keys including destination call numbers can be programmed; the active call diversion is indicated by a lit LED.
