Dialling the emergency number
The default setting for your phone is that
all numbers that are saved as emergency
numbers are automatically dialled using
the fixed network. The selected connec-
tion type (Internet or fixed network) is
irrelevant for dialling.
You can deactivate this function using the
phone's Web configurator (see dialling
rules, page 88), e.g. if you use the phone
without a fixed network. However, you
should ask beforehand, whether your VoIP
provider supports emergency numbers.
Emergency numbers have been preset in
your phone (it depends on the default set-
ting and country). You can use the Web
configurator to display these and to enter
another emergency number (page 88).
