Using Control Center, you can update the configuration of a SIP trunk service depending on your organization's needs. The status of the changed phone numbers momentarily shows as update until the changes are complete, when the changes take place immediately. You can also update a phone number to change its routing plan or to change its calling area.
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 checkbox(es) next to the phone number(s) you want to modify.
Select either Edit TNs Individually or Modify Multiple TNs, then click Go.
Using the lists in the popup window, edit which calls are being blocked (if any), the associated route plan, and/or the PPU location. You should also add contact information (name and email address) for the phone number—which assigns the number to the user.
Click the X to close the window (in the upper-right corner).
