   A call center uses Cisco UCM and has a route pattern '9.@' that allows users to dial any number after pressing 9. The management wants to block all calls to premium-rate numbers (e.g., 1-900) while still allowing all other national calls. Which configuration will achieve this with the least impact on existing call routing?

   • AAdd a route filter to the existing route pattern '9.@' that rejects any number starting with 900.
   • BModify the existing route pattern '9.@' to '9[2-9]XXXXXX' to only allow 7-digit local calls.
   • CCreate a translation pattern '91900XXXXXXX' with a discard digits instruction and route it to a null route, and ensure this pattern is in a partition that is included in the callers' CSS.
   • DDisable the '9.@' route pattern and create a new route pattern '9[2-9]XXXXXXXXXX' for national calls.
