What is Automatic Failover?

Automatic Failover is a Bandwidth feature that lets you send your inbound calls to an alternative phone number in the event a failure prevents them from being routed over your usual call routes. It offers increased reliability and peace of mind in situations where you would otherwise miss your incoming calls completely.

Note: Automatic Failover is different from our standard call forwarding feature, which lets you route all inbound calls from one of your Bandwidth numbers to an alternative number.

You can set up Automatic Failover on a Location or a specific phone number in the Bandwidth Dashboard. You can also add it via the Bandwidth Dashboard API using the Final Destination URI attribute.
