Caller ID Your administrator can set up your NBX system to allow for Internal and
External Caller ID or can configure the system so that you can block your
identity (telephone number) from anyone you call.
Internal and External
Caller ID
By default, the NBX system shows the extension and name of any internal
caller on the display panel of your 3Com Telephone.
External Caller ID provides the same information for external incoming
