...mber dialed into the "accountid" field. I'm trying to distinguish between failed attempts to register and attempts to dial without registering, but the security log treats them identically (using the accountid field for either the username or number dialed). I have noticed that the eventversion field is set to 2 for failed dial attempts, and 1 otherwise. Is this coincidence? Or can I rely on the eventversion=2 in the future to distinguish these two event types? (I've looked here: https://wiki.asterisk.org/wiki/display/AST/Security+Log+File+Format? but it doesn't really help) -...

Hi Ron, I don't remember right now, but you can try this command: cli> manager set debug off Cheers El 26 mar. 2017 3:58, "Telium Technical Support" <support at telium.ca> escribi?: I somehow cause AMI events to appear as output in the CLI, and I can?t figure out how to turn them off. Can someone offer a command which will suppress AMI events/commands from showing in

Just a note that I did a little work to extend FreePBX distro with some extra Fail2Ban which deals with some drive-by SIP registration attempts. My regex is poor to middling, but the steps detailed here: http://www.coochey.net/?p=61 manage to stop IPs which try to authenticate against Asterisk which FreePBX were not able to stop before. I would welcome any improvements anyone would care to

If this is a small site, I recommend you download the free version of SecAst (www.telium.ca <http://www.telium.ca> ) and replace fail2ban. SecAst does NOT use the log file, or regexes, to match etc.instead it talks to Asterisk through the AMI to extract security information. Messing with regexes is a losing battle, and the lag in reading logs can allow an attacker 100+ registration
