Phone User Interface
The phone user interface makes configurations available to users and administrators; but the Advanced/Advanced
Settings option is only available to administrators and requires an administrator password (default: admin).
You can configure the phones via the phone user interface on a per-phone basis.
Note: When you manually configure a phone via the phone user interface, the changes associated with non-static parameters
you make will be stored in the MAC-local CFG file. For more information on MAC-local CFG file, refer to MAC-local CFG
File.
