I added the following rules on iptables, but it does not work.
iptables -A INPUT -j BLACKLIST
iptables -A BLACKLIST -p udp -m udp --dport 5060 -m string --string
'friendly-scanner' --algo bm -m comment --comment 'friendly-scanner' -j
DROP
Any suggestions will be appreciated.

Hi,
blocking staticly on the "friendly-scanner" string might not be the
smartest way. Not everyone is so "friendly" to include the
"friendly-scanner" string.
fail2ban seems reasonably, or take a look at that tutorial by daniel:

might be easier to use fail2ban and let it deal with iptables.

You can simply drop or exit on User-agent, however as mentioned in above
thread it is not a proper solution changing a user-agent is not a big deal,
you may have to look into fail2ban, pike etc.
if ($ua =~ "friendly-scanner"){
exit;
}
