Displaying the Incoming Caller ID (CLIP)

The CLIP (Calling Line Identification Presentation) function

makes the number of callers—external and internal—visible

on your telephone display.

The CLIP function is enabled in the factory settings. This

function can be permanently disabled and enabled again.

Connected ISDN Line Identification Restriction and

Presentation (COLR/COLP)

By default, a caller’s display always shows the Multiple

Subscriber Number (MSN) of the extension she or he

dialed. Yet if you take the call at another extension, the

MSN of this extension will be displayed (see page 78). If

you do not want the caller to know that the call has been

picked up at another extension and thus wish this number

to remain concealed, you have the option of suppressing

transmission of the connected line’s number. The caller’s

display will continue to show the number that was actually

dialed.

This feature is only effective if your telephone supports

CLIP.
