82 CHAPTER 7: GETTING MORE FROM YOUR TELEPHONE SYSTEM Calling Line Identity Restriction (CLIR) On certain NBX systems, if your organization subscribes to Caller ID service from your local telephone company, you can choose to prevent the NBX system from transmitting your Caller ID information to outside parties when you dial a call. Your administrator must enable this feature, called Calling Line Identity Restriction (CLIR), on the NBX system. If this feature is enabled system-wide, you can choose to restrict calls: ■ For all external (outbound) calls that you dial OR ■ For only the next single external (outbound) call that you dial Your administrator can configure your system so that CLIR is always active, in which case you cannot change the CLIR settings on your telephone to override this option.

The display panel on your 3Com Telephone shows CLIR-ALL on. 2 Dial the number that you want to call.
