Multiple Call Handling
You can programme more than one MSN/DDI number to ring at an extension. If a call is
presented to your extension while you are on another call you will hear a Call Waiting tone,
provided your extension is programmed to receive Call Waiting tones. (See page 51).
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 38.
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.
