I have a new office that needs to fit in my four digit dial plan. The carrier is offering me choices of extensions that range from 1400-1500. I have tried to alter the destinations codes table to include a 1A in my existing BCM's but they won't accept it. Under the dialing plan/Public Network Settings the Public Network DN Lengths have an entry for the prefix for 1 and a DN length of 11. If I remove this entry you can't dial long distance. How do I get around this to allow the aforementioned extension range into the destination code table?
