Re: SIP attacks

You might consider using the Spamhaus DROP and EDROP lists 
<https://www.spamhaus.org/drop/>.  They eliminate a great deal of spam 
and probably a lot of those SIP fishing expeditions.  Because I turned 
SIP off before I discovered the lists, I can’t say for sure that they 
were responsible for the drop in SIP, but they certainly did reduce the 
clutter of other incoming attempts. Cheers,
