Mention Grandstream's "Disable Direct IP calls". Just had my first dodgy SIP call - despite the firewall rules
Solution: Firewall SIP as explained above.
 
Also some equipment may support the disabling of calls being sent direct from the Internet. For example, Grandstream firmware often has a feature ''Disable Direct IP calls'', which is worth using (unless you need to accept such calls).
