Feature Key Synchronization
Feature key synchronization provides the capability to synchronize the status of the following
features between the IP phone and the server:
 Do Not Disturb (DND)
 Call Forwarding Always (CFA)
 Call Forwarding Busy (CFB)
 Call Forwarding No Answer (CFNA)
If feature key synchronization is enabled, a user changes the status of one of these features on
the server, and then the server notifies the phone of synchronizing the status. Conversely, if the
user changes the feature status on the phone, the IP phone notifies the server of synchronizing
the status.
