My regex is poor to middling, but the steps detailed here: http://www.coochey.net/?p=61 manage to stop IPs which try to authenticate against Asterisk which FreePBX were not able to stop before.
I would welcome any improvements anyone would care to submit and I'll extend the article a little.
The changes need the Asterisk security log feature, which I think was only introduced in later versions of Asterisk (e.g. v11).
