You can use route filters to achive this, where you would have a local RF that would say something like
LOCAL-AREA-CODE == 111 OR LOCAL-AREA-CODE == 222 OR .....
or use wildcard masks in the route patterns, modiffing the following :
9.[2-9][02-9]XXXXX - local 7 digit
9.[2-9]X[02-9]XXXX - local 7 digit
9.[2-9][02-9]X[2-9]XXXXXX - local 10 digit
9.[2-9]X[02-9][2-9]XXXXXX - local 10 digit
9.1[2-9][02-9]X[2-9]XXXXXX - long distance
9.1[2-9]X[02-9][2-9]XXXXXX - long distance
