To check for availability of a new installation archive, use this command:

service webcallserver check_update

Updating the server can be done with one of the following commands:

a) service 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.

b) service webcallserver update yes

In this case, the server is stopped before starting the update without confirmation.
