System wide blocking of spam numbers to all extensions

There needs to be a way to block spam numbers from all extensions, phone numbers, and groups in one simple master place.

Spam has gotten out of control and when you get 100 spam calls per day to different extensions the current options of blocking to the extension one by one or filing it with the DO NOT CALL list does not help. Having to block it to each extension takes a lot of time and adding it to the Do Not Call Registry takes 30 days to process, which doesn't help because tomorrow it will be a new number spamming.

Please create 1 place where we can block a spam number accross all of our extensions.
