To check for availability of a new installation archive, do the following:

cd /usr/local/FlashphonerWebCallServer/bin
sudo ./webcallserver check_update

Updating the server can be done with the following commands:

cd /usr/local/FlashphonerWebCallServer/bin
sudo ./webcallserver update

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.

When updating WCS to builds 5.2.801-5.2.864, it is necessary to stop WCS manually after update to launch WCS as service:

sudo ./webcallserver stop
systemctl restart webcallserver

Since build 5.2.871, WCS is automatically relaunched as service after update.
