Calling Line Identity Presentation
Restriction (CLIR)
Calling Line Identity Presentation Restriction (CLIR)
allows you to prevent your number being displayed to
the person you are calling when you make a call on
your ISDN2 lines.
CLIR must be enabled on the network to allow this
facility to operate. This facility is only appropriate when
DDI/MSN is programmed. For non DDI/MSN lines the
network can set CLIR for all calls.

Enter the number and select ‘Send to Line’
The call is placed with the CLIR service activated.

Enter the PIN and select ‘Extensions’.

Connected Line Presentation (COLP)
Connected Line Presentation (COLP) is an ISDN
network service, which may be provided on your ISDN2
lines. If the service is available on your lines, it is
activated automatically.
COLP means that when a call is sent over an ISDN line,
the number of the line, which answers the incoming call
is displayed. This number may be different to the
number which the caller dialled if Multiple Subscriber
Numbering (MSN) is being used.
Connected Line Restriction (COLR)
Connected Line Restriction (COLR) is an ISDN network
service, which may be provided on your ISDN2 lines.
This service prevents the transmission and display of
the Connected Line Presentation (COLP) number (in
other words, the number of the line, which answers an
incoming call). The caller is therefore not made aware
that the call has been answered by a different number
to the number that they dialled.
