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.
