DND Synchronization for Server-side Configuration
DND synchronization feature provides the capability to synchronize the status of the DND features between the IP
phone and the server.
If the DND is activated in phone mode, the DND status changing locally will be synchronized to all registered
accounts on the server; but if the DND status of a specific account is changed on the server, the DND status locally
will be changed.
The following table lists the parameters you can use to configure DND synchronization for server-side.
