Summary:                    Console flooding caused by bad remote SIP peer
Description: 
Console is flooded by remote SIP peer.
This appears to be a Denial of Service attack using a mis-configured
remote SIP peer with no valid peer defined in Asterisk.

I know someone will say this can be fixed using iptables or fail2ban
etc...
But why must Asterisk reply to each SIP registration during this DoS
attack when their is no matching SIP peer configured in Asterisk?
