In Control Center, you can change termination numbers, NPANXX lines, states, or LATAs for existing geographic plans. You can also delete individual rules within the feature or you can delete the entire feature itself.
To update an existing geographic routing plan:
To change the terminating number or the terminating route type (e.g., switched or dedicated) for one of the rules, click the light gray bar for the rule, select the button for either DED (dedicated trunk) or SWI (switched ANI), select a trunk/ANI from the ANI list, scroll to the bottom, then click Update. (If you don't see the trunk/ANI you need, click the ADD ANI TO THE LIST button and fill in the fields, click Add.)
