sip attacks


My asterisk server is getting bogged down every 5 minutes. My ping time is
going from 60ms to 800 ms and the call quality is bad. I have fail2ban running and I am using iptables. I have two ip connections

any reg attempts in my asterisk cli. I use to get frequent attacks but
fail2ban seems to be taking care of that. See how ping time gets worst in a short space of time and server performance
