To start the update you will need to confirm stopping the server.
If a new installation archive is available, it is downloaded to the /tmp directory and the update of the server is then started using install.sh -silent.
After the update completes, an update message is shown and the server is started.
sudo ./webcallserver stop
systemctl restart webcallserver
Since build 5.2.871, WCS is automatically relaunched as service after update.
