Subject: [Freeswitch-users] sip auth challenge HACKING ???

Hi FS Users,

in last time i see in my console of FS this kind of error messages.

[WARNING] sofia_reg.c:1246 SIP auth challenge (INVITE) on sofia profile 'internal' for [5828@?????????] from ip ???7?.1??.7??.???

i check my config files ever again and again, but today the console is only given this kind of messages. Maybe 20 messages per second.

i see the ip that given in the console "from ip xx.xx.xx.xx" i block this ip in my firewall and everything is fine.
Now i understand that this a trying to hacking my server. The blocking of the ip is a solution but can not handle this in Freeswitch, because i see this problem sometimes on different FS servers also and in normally the FS server maybe must can handle this problem. For example with automatic black lists if an ip trys more than 20 times with wrong login. So the ip will be banned for 1 hour or so.

i'm interesting in if other users have the same problems and ideas in how we can handle this.

Kind regards
Erkan
