Call Forward Synchronization for Server-side Configuration
Call forward synchronization feature provides the capability to synchronize the status of the call forward features
between the IP phone and the server.
If the call forward is activated in phone mode, the forward status changing locally will be synchronized to all
registered accounts on the server; but if the forward status of the specific account is changed on the server, the for-
ward status locally will be changed.
The following table lists the parameters you can use to configure call forward synchronization for server-side.
Parameter
features.feature_key_sync.enable <y0000000000xx>.cfg
