Beginning on January 6, it appears that somebody has been trying to hack into

I'd restrict access to the Asterisk box using iptables (or similar
firewall) and only allow access from trusted client IPs or networks.
This only works though if you know the originating IPs (and/or
networks) of client connections and that they don't change over time.
