Customizing the calling area for a phone number

For phone numbers on a Lumen® SIP Trunking service, you can customize the allowed calling area by phone number in Control Center. For example, you can block all outbound calls for a number except to local numbers or you can allow long‑distance calls, but not international calls. This helps you control the numbers a user assigned to the number can call.

To customizing the calling area for a phone number:

  1. Click Services.

    Control Center shows the Services console. Use the console to access an inventory of your services, check the status of orders, and manage your services.
