This is just "security by obscurity" and of course your SIP proxy 
configuration must be secure to handle such scanning attacks.

Nevertheless these scans are annoying and using a non-default port is a 
good practice. You can change the port easily with the "listen" 
directive, see http://www.kamailio.org/wiki/cookbooks/3.3.x/core#listen

Further, this snippet at the beginning of your config may help too:

         # ignore requests generated by sipvicious
         # User-Agent: friendly-scanner
         if ($ua == "friendly-scanner") {
                 exit;
         }
