it is extremely dangerous to ban IP based on a suspicious UDP activity. The
source IP of an UDP packet can be easily forged, so if you start using
fail2ban or other blacklist techniques, it can be very awesome to start
sending bogus invite and let you blacklist all major SIP providers...

However I am using fail2ban on all my servers :-)
