78CHAPTER 6: GETTING MORE FROM YOUR TELEPHONE SYSTEM

Internal and External By default, the NBX system shows the extension and name of any internal Caller ID caller on the display panel of your 3Com Telephone.

External Caller ID provides the same information for external incoming calls if your organization subscribes to the service from your local telephone company and if the caller has not blocked the information from being sent to the NBX system.

Availability and service charges for External Caller ID vary by location.

Calling Line Identity On certain NBX systems, if your organization subscribes to Caller ID Restriction (CLIR) 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.
