Call Forwarding 
20
Warning users if their calls are redirected
You can warn analog phone users if they have features active that may redirect 
calls. For example, if the user has activated call forwarding, you can administer a 
setting to play a special dial tone when the user goes off-hook. See 
‘‘Special Dial 
Tone’’ on page 656
 for more information. 
Security
Use the 
list call-forwarding
 command to get general information and to identify 
unauthorized Call Forwarding feature activation. The list shows the station name, 
station number, and forwarded-to destination number.
!
SECURITY ALERT:
Users who do not have permission to call out of the building may not do so 
with Call Forwarding. 
Considerations
Calls can be forwarded only once. Consider the following scenario. Extension A 
forwards its calls to extension B. Extension B forwards its calls to extension C. 
Calls made to extension A:
Ring at A, if possible
Ring at B, if possible
Redirect to extension A’s coverage path, if available and A’s coverage 
criteria are satisfied when applied at B
Are not forwarded to extension C
There is no maximum number of calls that can be forwarded simultaneously.
You can administer a phone to receive a redirection notification signal when a call 
is forwarded.
The system restricts users from forwarding calls to a number that they are not 
allowed to call.
If 
save translation
 is run after call forwarding is activated for a phone, 
forwarding status and destination number are saved to tape.
