Telephone system:fail2ban

For the telephone system, apart from the (mild) default fail2ban freeswitch filter, two additional filters are created (Source: http://wiki.freeswitch.org/wiki/Fail2ban):

/etc/fail2ban/filter.d/freeswitch-dos.conf

[Definition]
failregex = \[WARNING\] sofia_reg.c:\d+ SIP auth challenge \(REGISTER\) on sofia profile \'[^']+\' for \[.*\] from ip <HOST>
ignoreregex =

/etc/fail2ban/filter.d/freeswitch-ip.conf

[Definition]
failregex = \[DEBUG\] sofia_reg\.c:\d+ sofia\/external\/.+@\d+\.\d+\.\d+\.\d+\ receiving invite from <HOST> version
ignoreregex =

/etc/fail2ban/jail.local

# ban for a week
