Description

If enabled, the SIP server manages Call Forwarding Busy (CFB) for this SIP account (identity), i.e. the target number is set via the management console of the SIP server. The same way one can then activate/deactivate the feature.

The UI will show the current setup if the server synchronizes it's values with those on the phone (state and target). This setting does not specify how the server changes the redirection values nor how the phone updates them. (it may be done via TR69, DFKS or starcodes).
