Well, in my case it's all TCP, so once the INVITE is received there's a connection setup, the challenge SHOULD arrive. And in any case, i won't just block it, it would have to happen several times.

Thats probably a bad idea to just block those, there are legit situations where they won't respond, especially nat clients, that may not received the challenge and can't answer the challenge, All I sense this doing is driving some poor support tech batty.

Hello,

Thanks for your reply. I already use fail2ban to block IPs that FAIL to register, this means there's a response to a challenge with a bad password hash.
But in my case there's no response.

There's an INVITE and fs responds with 407, but the attacker never answers that challenge, so there's no log of a failure that can be used to block the ip.

I don't see a feature where this can be done specifically. Can you please explain?

Thanks a lot.

David

This may be done using fail2ban and mod_fail2ban
