Adding direct‑trunk overflow to a routing plan

If you want your customers to talk to someone rather than get a busy signal, use the direct‑trunk‑overflow feature to ensure callers terminate on a DID/ANI ring‑to number. If your business needs change, you can remove direct‑trunk overflow from the routing plan later. You can also use busy ring no answer (BRNA®) in conjunction with direct‑trunk overflow.

To add direct-trunk overflow to a routing plan:

  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.
