Under what conditions is the auto failover to the secondary invoked, and what is the secondary on the dial plan?

When your business-as-usual (primary) location becomes inaccessible or inoperable, the smartnumbers service ensures that calls continue to be delivered to a pre-determined secondary location.

If you use the smartnumbers directed recovery service or the smartnumbers protect service, the service administrator must invoke the service.

If you use the smartnumbers proactive recovery service, or the smartnumbers control service, this failover to the secondary location happens automatically. When the service cannot deliver calls to the primary location, calls are automatically re-directed to your secondary location defined in the dial plan.

You can view, edit and invoke your dial plans using the Smart Business Portal.
