Suppressing Caller ID for Outgoing Calls (CLIR)
Suppressing Caller ID for Outgoing Calls (CLIR)
The CLIR (Calling Line Identification Restriction) function
prevents your telephone number being displayed on the
other party's telephone during outgoing calls.
The CLIR function is disabled in the factory settings. You
have the option of enabling this function permanently and
then disabling it again. CLIR can also be used for individu-
al connections. When CLIR is permanently enabled, this
setting is saved for the extension and always enabled for
outgoing connections.
If you would like to conduct only certain calls with the Call-
er ID suppressed, prefix the number dialed with a keypad
sequence. This enables CLIR only for the current connec-
tion.
