Thank you for your quick replay.<br>
Could you tell me please how do you come to this conclusion?<br>
and if this is a brute-force, it can make my system slow all the

Somebody is trying to break into your freeswitch box. Just find
that user's ip and block it in IPTables.<br>
<br>
If problem persists and hacker comes from another IP then you
probably need to configure Fail2Ban service.<br>
<br>
Thank you.<br>
