9. 7. 7 Suppression of the call number display
The display of the call number to the called party can be suppressed (CLIR). CLIR can
be permanently activated or deactivated for each user in WebAdmin. Each user can
also use a */# function code to activate or deactivate CLIR either permanently or only
temporarily for a single call.
Detailed description of temporary CLIR
CLIR is activated temporarily using *31 before dialling an external call number. If CLIR
is already permanently activated, it can be deactivated temporarily using #31 before di-
alling. The permanent CLIR settings are restored once the call is completed.
Scope
Suppressing call identification is supported only for external calls via digital network in-
terfaces with the DSS1 protocol.
Notes:
– The function is not executed when used in connection with ISDN supplementary services in
the exchange such as ECT, PARE or CD, i.e.the call number is displayed to the called party.
– Depending on the network provider and service provider it may be necessary to subscribe to
CLIR.
Suppressing the call identification is not possible in the following cases. The outgoing
call is rejected; the display reads Not available and the user obtains the busy tone:
• External calls via analogue exchange interfaces
• Internal calls, calls to PISN users or virtual network PISN users
• In combination with an abbreviated dialling that contains other */# function codes
• In combination with dialling using a line key
