Given an internal directory number, how do you find the External Number that Cisco call manager would direct to it?
We have a large spreadsheet of available numbers with associated Externals Masks beside it, but a portion are wrong. I'm looking for a way to get external mask from the call manager without relying on the spreadsheet of numbers. It would then be added to the External Mask Field when creating a DN for that number.
Looking through route plan report, I can search through translation patterns for the external numbers, but cannot search by the new translation/internal numbers. This makes finding the internal given external feasible, but not the other way around.
As a followup question, is there some way search for translation patterns that match a given number, or to check what the final internal number of an external incoming call would be without test calling it?
