trunk or intercom calls. Intercom calls receive busy tone; trunk calls are 
routed to the extension defined in permanent call forwarding.

The following types of incoming trunk calls will follow permanent call 
forward settings:

-  Direct trunk calls (including DID/DNIS)

-  Transferred trunk calls.

• With CPC-A and CPC-B Version 1, DND is not available for Attendant 

Phones. Beginning with CPC-B Version 2.0, Attendant Phones can 
activate DND. 

• The Attendant can activate or cancel this feature on an extension using FF 

key LEDs on a DSS console.

• The DND feature cannot be activated from an extension selected to receive 

call forwarding.
