along with all the previous suggestions.. i found out that fail2ban is a good
safe tool to be used along with hard passwords and not using numeric
usernames.. for me using A2Billing along with Asterisk was a pain because it
needs to create usernames numeric.. so i had to create strong SIP users and
passwords then assign a2billing accounts to them to make it safer.. plus the
fail2ban .. give it a try.
