Extension Locking
Description
Extension Locking allows a keyset extension user to secure their phone when they leave the office. The user
may want to do this if their phone has Toll Restriction and Class of Service options enabled that could be
easily abused. While locked, the restrictions set up in Class of Service 15 and Toll Level 7 are in force at
the extension. When the user returns, they just unlock their extension to return it to normal operation.
You’ll need to program the restrictions in Class of Service 15 and Toll Level 7 separately. See the Class of
Service (page 88) and Toll Restriction (page 351) features for more.
Walking Class of Service and Extension Locking
Walking Class of Service overrides Extension Locking. For example:
❥ Extension 301 is permitted by their Class of Service and Toll Restriction to use Paging and place long
distance calls.
❥ Extension 306 locks their extension. While locked, Class of Service 15 prevents Paging and Toll Level 7
prevents long distance calls. These features are no longer available at extension 306.
❥ The extension 301 user goes to extension 306 and implements Walking Class of Service.
❥ The extension 301 user can then use 306 to make long distance calls and Page (even though 306 was
locked to prevent those features).
