<p>Another alternative is SecAst (Asterisk intrusion detection system). Grab the free version from
<a href="http://www.generationd.com/">www.generationd.com</a><br>
</p>
<p><br>
</p>
<p>It does everything fail2ban does, plus you have the option of blocking IP's based on geograhic origin, detecting suspicious call patterns, etc.<br>
