They couldn't deal with that.
I'll just very quickly go back to the idea of malformed numbers. If you're getting numbers that aren't real phone numbers, full of a bunch of zeroes because scammers are sending calls through the system using phony numbers, or they're all fives or they're all fours, it doesn't matter what it is; they know it's not a real call. If that goes to the RCMP.... It's not a crime to try to use all fours to go through.
