Is there a way to stop this or slow it down. I thought I remembered someone saying there was something that could be changed like returning a 200 ok on a ban. I am concerned about how this will impact sipwise since it is already showing signs of stress.

  Look for the below in your 

change_reply_status("403", "Blocked, banned and reported");

  Now comment that out and insert this right below it

change_reply_status("200", "OK");

so now you should have...

#change_reply_status("403", "Blocked, banned and reported");
change_reply_status("200", "OK");

Save, then ngcpcfg apply and that should do it for you. This will 200 at 
ban time and hopefully throw off the scanner with an OK.
