Station Lock (F21)
Description
This feature is available only on system and standard touch-tone phones.
This feature lets users enter a four-digit code on their telephone dialpad to “lock”
their extension. Later, the user enters the identical code to unlock the extension.
Station Lock helps to prevent unauthorized people from making outside calls from
these extensions. You should recommend that users lock their extensions
whenever they leave their desks for extended periods of time.

■ All outside numbers except Marked System Speed Dial Numbers and
numbers on the Emergency Phone Number List (#406) are restricted
from locked extensions.
■ If a user forgets the code, use Station Unlock to unlock the extension.
■ Do not lock External Hotline extensions.
■ Station Lock returns to the status (on/off) it was in before a power failure
occurred or System Reset (#728) was used.
■ You cannot use the Caller ID Call Logging and Dialing feature when your
extension is locked.
■ For security purposes, use this feature to prevent misuse of Call
Screening (F25).
Considerations
■ You can program a Station Lock button on a system phone. A button with
lights is recommended, so the user can quickly determine whether or not
the extension is locked.
■ Users can enter a different code each time they lock their extension.
■ A user at a locked extension can make intercom calls and can receive
intercom and outside calls.
