Setting and dialling emergency
numbers
You can save up to five emergency num-
bers on your phone. The default setting
for your phone is that these emergency
numbers are always dialled via the fixed
network – irrespective of which connec-
tion type you select. The fixed network
always supports general emergency num-
bers (e.g. establishing connection to the
local police emergency number).
You can deactivate the setting for emer-
gency numbers to always be dialled via
the fixed network ( Dialing Plans , page 27).
However, you should ask beforehand,
whether your VoIP provider supports
emergency numbers (e.g. the local police
emergency number).
You can enter or change emergency num-
bers in the Web configurator on the Dialing
Plans Web page.
