In trying to find the call flow on CUCM 6.1, the DNA kept showing Block this Pattern for all DNs in all Calling Search Spaces. Yet, the users were able to make calls. I have seen this in other instances as well. The DNA shows Block this Pattern when the users are, in fact, able to make calls. Is this a bug with the DNA? Is there a way to get it to work so I don't have to manually trace the call flow? Thanks.
