OK so I found the offending IP address out of South Brisdane, Queensland. They are just going thru 4 digit extensions one by one, they file is quite large. What should I do next? Block the IP and report it?

As most would say "you're dealing with script kiddies"  people that are trying to find a free route for the calls among other mischievous things.

Check the file /var/log/asterisk/messages for some helpful clues where the attempts are coming from.

Look for SECURITY[numbercode]   there should be some ip addresses on the same line.

You can find out more about the ip address and the subnet involved by going to: http://mxtoolbox.com/arin.aspx and enter the ip address.

Do you know how to set up the iptable rules?

It's more of a nuisance than anything else.    Still a good idea to learn how to use iptables, it will make things easier in the long run.
