Joel Vandal commented on ASTERISK-22540:
----------------------------------------

We added a new rules on Fail2ban in order to block the attack that cause server to crash. 

We will try to get SIP logs next time we got flooded .. and check if we can easily reproduce the flood, but look easy to crash any servers.
