Cisco CUCM 10: Can you block an incoming call using just a translate pattern

I've been trying to block calls from a specific number that comes in from the PSTN over a SIP trunk. I am trying to use the "Block This Pattern" feature within Translation Pattern Configuration to make this happen. The process I read on the support forum below would have me making more changes than I want to do and I don't have a lab to make sure it wouldn't harm something. I just want all calls from a specific number to hit the bit bucket. Could I do it with just a translation or other simpler method?
