How do we block hacker with the linux box?

In the sample of sip.conf, it shows

1. ;       Especially note the following settings:
   
2. ;               - allowguest (default enabled)
   
3. ;               - permit/deny - IP address filters
   
4. ;               - contactpermit/contactdeny - IP address filters for registrations
   
5. ;               - context - Which set of services you offer various users
   
6. ;

Therefore we can use allowguest, permit/deny, contactpermit/contactdeny to prevent hacker if we know their ip.

I forgot the way to include a file which contains the blacklisted IP addresses. If you know, please let me know the method.

I believe we have to read the source code to determine the configuration in detail.
