If the attacks are direct (rather than through Asterisk) and you have a Polycom phone, check around page 522 of the firmware 4.0 admin guide.
If the attacks are directed at your Asterisk then you should use fail2ban to dynamically block attackers. If the attacks are coming to your phone via Asterisk then you have a security issue in your Asterisk config. -----Original Message----- From: asterisk-users-boun...@lists.digium.com [mailto:asterisk-users-boun...@lists.digium.com] On Behalf Of motty cruz Sent: Monday, May 12, 2014 5:43 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: [asterisk-users] Asterisk 1.8.22 Hello, recently I have seen spike in attacks on my asterisk server, this is what I get on the LCD of my phone: 201@76.220.5.205 or calls from 1000 sip1000@76.2230.5.205, have any idea on how to stop this calls?
