[asterisk-users] Auto ban IP addresses

[Frank]

Greetings all,

I have been seeing a lot of

[Jan  2 16:36:31] NOTICE[7519]: chan_sip.c:23149 handle_request_invite: 
Sending fake auth rejection for device 
100<sip:100 at 108.161.145.18>;tag=2e921697

in my logs lately. Is there a way to automatically ban IP address from 
attackers within asterisk ?


Thank you
