A single route pattern has been added to the Cisco Unified CallManager to use the NANP. A route filter named Local_Only has been applied to limit calls to local and service numbers only. The Local_Only route filter includes the clause: (LOCAL-AREA-CODE EXISTS AND SERVICE EXISTS). After applying the Local_Only route filter, no calls to the PSTN can be completed.
What needs to be done to correct this issue?
A.
Two separate route filters need to be applied to the route pattern, one for local calls and one for services.
B.
The route pattern needs to be added twice, once with a route filter for local calls and once with a route filter for services.
C.
Route filters cannot be used to allow multiple call types. Specific route patterns for local calls and services need to be added.
D.
The route filter clause should be changed to (LOCAL-AREA-CODE DOES-NOT-EXIST AND SERVICES DOES-NOT-EXIST) and the route pattern should be set to block calls.
E.
The route filter clause should be changed to (LOCAL-AREA-CODE EXISTS OR SERVICES EXIST).
