Hello list,
I often see the following in my message log :

And there are hundreds of them...
Is there a setting so I can make Asterisk not respond to SIP PEER
registrations which are not in my sip.conf or my realtime MySQL DB ??
Yes, you add a rule to your firewall! Even better, get it filtered
further out so that it does not waste your inbound Internet bandwidth,
because in my experience, once those SIP spammers start, they continue
for weeks at the very least.
IIRC, the way SIP registrations works basically requires than an
failed/un-authorised attempt is responded to, so that the other party
knows to authenticate. If you stop sending that response, no-one can
authenticate.
Hope that helps.
Steve
So in short, there is no way of throwing away registrations that are not
in sip.conf.
The only thing I can do is check the messages file now and then to see
if there were bad registrations, and then blacklist them.
Kind regards,
Jonas.
