Hi we have a FreePBX Voip pbx which is running quite okay; Everyhting is functional and working but we often get calls from fony/faxe extensions . It happens that on 1 extenions like 15 lines are ringing all at once from extension 100 Last week we got calls from extenin 33400 then 33500 then 33600 then 33700 etc... I disconnect the phone so the ringing stops. After 1 hour I connect it again now calls frol 44100 > 44900 Disconnect the phone again. 1 day later no calls anymore. If I pickup a call nothing happens. It is like a bot or something trying to do something; Who can fix this or knows what to look for? When I check the CDR log I cannot see the originating call. I cannot tell when it happens or why. But it is really annoying.

Hi, from the description it's safe to asume that you are receiving calls from hosts that are trying to exploit misconfigurations on your PBX. These calls are trying to figure out if any of your extensions has a simple password or if outbound routes are enabled for external calls. After a quick survey on your configuration, I will be able to configure FreePBX to reject this calls, do a hardening of Asterisk to avoid know security issues and - if neccesary - add some rules to your firewall or deploy a process to block any IP trying to access your server. Please feel free to contact, I'm available to discuss you how I would do this task. Best regards, Emanuel.

Hello, hey I am also from belgium! ;) Have you tried disabling the "allow anonymous incoming calls"? I guess someone is trying to scan for valid extensions to later use it to call using your credit.. also, it's good to use fail2ban, I have many asterisk PBX, if you don't secure them thoroughly they quickly get hacked and it can cost you thousands of euro.. Also, don't rely on the CDR to debug this kind of issue, as the CDR can fail at many levels, you should check the logs in /var/log and leave an asterisk CLI connected.. asterisk -rcvvvvvvv I am looking forward to help you fix this issue.
