An engineer has hundreds of H.323 gateways with thousands of route patterns in a Cisco Unified Communications Manager cluster. The engineer has noticed many specific route patterns created to the H.323 gateways. Which digit manipulation method on route patterns is most effective in reducing the number of route patterns?
A. regular expressions
B. prefix digits
C. called-party transform mask
D. discard digits
I think the key in this question is the part that said “reducing the number of route patterns?””
with Regular expressions or Wildcards you can do that.
but Im Little confuse, because the Question mentioned Digit Manipulation Methods.
regular expressions allow a single route pattern to match a range of numbers, also to build instructions that enable the CUCM to manipulate a number before sending it to an adjacent system.
I think A is correct
I agree
