Defining authorisation
You can set different authorisations for all registered devices:
◆ Unrestricted (set as factory default)
All devices can answer incoming calls and make outgoing external/internal calls.
◆ Incoming only
The devices can only answer incoming external calls. External outgoing calls are not
possible. Internal calls (outgoing and incoming) are possible. Emergency numbers
can be dialled.
◆ Internal only
The devices can only be used for internal calls (incoming and outgoing). Emergency
numbers can be dialled.
Emergency numbers
By default, the country-specific emergency numbers are entered. You cannot change or
delete these. You can enter five emergency numbers of your own.
