Preventing

of Your Telephone
To prevent others from dialing long-distance or other unauthorized calls 
from your telephone permanently, ask your administrator to adjust the 
call permissions schedule for your extension, or you can adjust it 
temporarily with the Telephone Locking feature.

Additional Notes
■
When Telephone Locking is activated, a person using your telephone 
can dial only toll-free calls, calls to emergency services (such as 911 in 
the United States), or calls to telephone numbers that have been 
programmed in your system as “internal” calls.
■
Even when Telephone Locking is active on your telephone, your 
off-site notification choices remain in effect. That is, notification of 
voice mail messages is sent to the outside telephone numbers or 
paging numbers that you have specified in the NBX NetSet utility NBX 
Voice Mail Settings > Offsite Notification page, even if these 
numbers are not toll-free.
■
You can view your current Telephone Lock setting from the NBX 
NetSet utility by going to the My Calling Privileges > Feature 
Settings.
