Calling Line Identity (CLI) services

Calling Line Identity (CLI) services are ISDN services available from your ISDN
Network Provider. You must contact your Network Provider and subscribe to these
services before their functionality is available to the BT Versatility.
The Calling Line Identity Presentation (CLIP) service provides that, when you receive an
incoming call on your ISDN lines, the caller's number is presented to the BT Versatility.
This number, (or name, if a name has been associated with the number), is displayed on
all Featurephones programmed to ring. It is also displayed on any standard phones
capable of detecting CDS. In addition, you can store caller numbers, dial stored
numbers, and route incoming calls to extensions based on the caller number provided.
For information on using these features, see page 32.
Your number will also be presented to the person you are calling on an ISDN line, if they
subscribe to the CLIP service. The Calling Line Identification Restriction (CLIR) service
allows you to restrict the network from presenting your number.
The Connected Line Identification Restriction (COLR) service prevents the transmission
of your number to the caller when you answer a call. Contact your Network provider for
further information.
