As soon as I have installed asterisk I saw some hackers trying to break in to the system. Can someone recommend some guide to prevent hackers getting in by using bruteforce attacks?
This is not the issue of upgrade SERP. But serverip.dat in this case contains the value: 192.168.88.12:1301, so this is local IP of the server with SERP.
Anyway I don't understand what do you me...
