If you think there is a need for this in a production environment, I'd like to see corresponding manager actions, as well, since we don't want to encourage the usage of CLI commands from programs when possible.

If you use distributed device states its possible to get notifys from different asterisk servers, cause the subscription was sent to another asterisk in the cluster, before the old subscription timed out.
