White list?

I know there is a blacklist in FreePBX. But is there a whitelist feature in FreePBX? I moved my home phone number to my FreePBX 12 system. We were getting 90% telemarketers even though we are on the DNC list.

I want only people on my whitelist (family, friends, etc) to ring through and all others (ie telemarketers) to go to VM. I know I can set up incoming routes for each phone number, but I am talking about a list of about 20 numbers. The other option is bulk incoming routes.

Thank you!
