Blocking unknown numbers

I did a search ont he forum and found a posting on using the extensions_custom.conf to filter unknown numbers. I posted it below so everyone could see what I am talking about.

In this conf file, if a call isn't filtered, it is passed off to que 7201. Is there a way to changet this to go back to my ring group? We don't use a que so I would rather this go back to ringing my extensions. Is this possible?

Thank you.
