Note that the CLIP function usually has to be activated by the network operator.
To request this function, key in *#30#.
Calling Line Identification Restriction (CLIR)
The CLIR (Calling Line Identification Restriction) feature offers the user an op-
portunity to prevent his/her number from being shown to the B subscriber.
The network operator sets the CLIR either to ON or OFF state for the subscriber.
It is also possible to revert to the CLIR status for one call at a time.
If, for example the CLIR is disabled (that is a phone number will be shown to the
called person), invoke the CLIR by keying in #31#PhoneNumber
.
The phone makes a normal call to the PhoneNumber but the B subscriber will
not be able to see the Nokia 22 phone number.
If the CLIR has been set permanently to the ON state (that is the phone number
is normally never shown to the B subscriber), key in *#31# to show the number.
Call forwarding (Call offering)
These functions allow the user to forward incoming calls.
Table 10: Call forwarding functions
• Unconditional call forwarding, also called call offering, allows incoming calls
to be directed to another number (network service).
