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 services 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 SIP trunk service you selected.
Click the Telephone Number Management tab.
Control Center shows the telephone number(s) for the service.
Select the checkboxes next to the phone numbers you want to modify.
From the Select Action list, select Download to Bulk Load.xls, then click Go.
Control Center emails you a link to OPEN/SAVE an Excel spreadsheet. The second tab of the spreadsheet includes instructions for how to complete your bulk upload. (You can assign users, modify allowed call types, or reassign routes on all selected numbers—which is intended to make management easier.) Be sure to save a copy of your work to your computer before you upload the document.
When you're done editing the Excel spreadsheet, select Bulk Load (from the Select Action list), then click Go.
Select the file you want to upload.
Control Center validates the file, starts processing your changes, and emails you a confirmation.
