One Click Failover

This allows customers to still receive critical or valuable inbound calls until connectivity is restored individual and contact center users as well as automated attendants. When this option is enabled, all predetermined programmed Teams numbers from that organization will forward to the user-specified alternative device/application. When the connection is restored, within seconds a customer can simply uncheck forwarding, press save, and all forwarding will be removed.
