◆
Unrestricted

All devices can answer incoming calls and make internal/external calls.
◆
Incoming only
The devices can only answer incoming calls. External calls are not possible. Internal
calls can be made. Emergency numbers can be dialled.
◆
Internal only
The devices can only make and answer internal calls. Emergency numbers can be
dialled.
Emergency numbers
By default, the country-specific emergency numbers are entered (No. 117, 118, and
