Click Services, then click Network, Security, and Communications.
Control Center shows a list of all services assigned to the billing accounts under the enterprise ID.
Search for the service in one of these ways:
Start typing details for the service (e.g., the product name, location, or service ID). Control Center filters the list of services as you type.
Filter your services by selecting an option from the All Service Types list.
To filter your orders based on a specific value, select an attribute from the Advanced Filters icon (), click the section(s) you want to filter by, type your filter criteria, then click Apply.
When you find the service you want to work with, click the hyperlinked service ID or click the icon (in the Actions column), then click View Details.
Control Center shows details for the toll-free service you selected.
From the Call Plan More Actions list, select Edit Call Plan.
Important: In the Call Plan More Actions list, you may see an option for Terminating Addresses. Use this option to add a switched terminating address or to change the DNIS value for one or more trunk groups.
Click the Global Default gray bar 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 either the DED (dedicated trunk) or SWI (switched ANI) radio button.
From the Primary Trunk list, select a trunk. (If you don't see the trunk/ANI you need, click the ADD ANI TO THE LIST button, fill in the fields, then click Add.)
Scroll to the bottom of that box, then click Update.
