USB lock
Although the USB port allows the IP Deskphone to extend peripheral support without hardware
changes, the customer is required to lock the USB port in compliance with the corporate
security policy. The lock can be applied on the USB port to disable all USB devices, or it can
be applied on individual types of USB devices.
USB Locks preference menu
You can override the system configurations on the IP Deskphone through the USB Locks
screen. The USB Locks screen allows you to override the USB lock configurations in the device
configuration file to enable or disable the USB port. If the USB Locks Override is enabled and
the USB port is not disabled, you can individually lock or unlock the supported USB devices
on the IP USB Locks.
To access the USB Locks screen, from the Preference menu, choose USB Locks. The
protected Administrator password is required.
