play
You do not want your call number to appear on the terminal display of a called party
in the public network.
You have two possibilities:
• If you never want the phone number to be displayed, set CLIR Permanent .
• To suppress your call number display for certain calls only, select the function CLIR

You can also execute the function with a */# procedure (see "User’s Guide */# Proce-
