Emergency numbers
Dialling plans for emergency numbers (e.g. the local emergency service number) are fac-
tory-set for certain countries. The fixed line network is determined as the Connection Type.
These dialling plans cannot be deleted, deactivated or blocked. However, you can change
the Connection Type.
This should only be changed if the phone is not connected to the fixed line network. If you
choose a VoIP connection, please make sure the VoIP provider supports emergency calls.
If no dialling plans for emergency numbers are preset on your telephone, you should set
dialling plans yourself. Assign them to a connection that you know supports emergency
calls. Emergency calls are always supported by fixed line networks.
Please note:
Predefined dialling plans set as defaults (for emergency numbers cannot be deactivated and cannot
be deleted.
Warning:
– Emergency numbers cannot be dialled if the keypad lock is activated. Before dialling, press and
hold the hash key to release the keypad lock.
– If you have activated an automatic area code and if no dialling plan for emergency calls is defined,
the area code will also be prefixed to emergency calls made via VoIP.
