By selecting Start, and then restart, the system can be rebooted.
Selecting Shut Down instead of Restart would result in the system shutting down
If the GUI is inaccessible, the system can safely be rebooted using the “sudo reboot” command.
Stopping Asterisk using the ‘sudo asterisk r “stop when convenient” ‘ command, is
recommended. This stops the Asterisk service as soon as no calls are in progress
and ensures that rebooting the system does not affect any active calls.
