The SIP trace shows messages from what I took to be a suspicious
connection from sip:[email protected] so I added that IP address to IP
tables...but then anveo showed as unreachable so I removed that rule.
Yes, I'm running fail2ban.
What are these messages from sip:[email protected]? The domain name alone
set off alarm bells for me. (I was looking for my own registration
attempts when I turned on SIP debugging.)
