Tip: With fixed dialing, you can, for example, restrict calls to certain areas. In this case, type the area code in the
Number
field.
To specify how an unknown incoming call is received, scroll to
Default call mode
. If, for example, you select
Voice call
, an incoming
call is treated as a voice call where the network is unable to identify whether the call is a voice call or a fax call. This may occur
if the caller's telephone and fax have the same number. This setting is not available in all regions.
To change the phone line for outgoing calls (network service), scroll to
Telephone line in use
, press
Change
, and select the phone
line. To be able to use this function, you need a SIM card that supports the alternate line service and a subscription to two phone
lines.
To prevent the phone line selection, scroll to
Block line selection
, press
