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. After the service has failed over to your secondary location, you can switch between dial plans to divert calls to agents’ current locations.
You can keep the dial plans active for as long as you need to. However, any calls will be charged at a rate higher than your normal telephone charge.
