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.
Control Center displays a list of all services assigned to the accounts under your enterprise ID. If you have more than 10 services, you can view the rest of your services by clicking one of the blue linked Show numbers at the top of the list or you can click the blue down arrow at the bottom of the list to add 10 services at a time to the view.
Search for the service in one of these ways:
Sort your services using the Sort by… list (e.g., Service Type). You can toggle between descending and ascending order using the arrow to the right of the Sort by… list.
Filter your services by selecting an option from the View All (Default) list.
Search for a specific service (by service type, account, etc.) using the Search by… field and search box. (To search using multiple search criteria, click Advanced Search, then fill in your search criteria and click Apply Search Filters. When you're done, click Close Advanced Search.)
When you find the service you want to work with, click the black arrow on the right of the line for the service.
Control Center displays details for the SIP trunk service you selected.
Click the Telephone Number Management section.
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 pop-up 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).
