We are having an issue where we have unassigned DID phone numbers that all end up at one directory number, but then if we setup a translation patterns for that DID, then it routes to the directory we just assigned it to. We are trying to see if there is a way to have all unassigned DID numbers go to a not in service voice recording. We are running CUCM 12.5 and our voicegates are Cisco 4351 using SIP trunks. I know we have voice class pattern-maps configured on the voice gateways, as e164 ^3162184[2-8]..$ but don't know where those are getting pointed at in CUCM. I have searched for these numbers in the route plan report but they don't show up.
