Failover to New enum-config

When an enum-config’s configured servers are unreachable via the network, i.e., no response is received on a query, the Oracle® Enterprise Session Border Controller can failover to a defined ENUM config that contains different enum servers to query. This failover behavior works when all servers in an enum config are unreachable, rather than when the Oracle® Enterprise Session Border Controller receives not-found type responses.

The Oracle® Enterprise Session Border Controller queries each ENUM server once before trying the next configured server, and then ultimately trying the servers listed in the failover-to enum config. If the failover-to servers also are unreachable, the Oracle® Enterprise Session Border Controller fails the call; the failover-to behavior does not recurse among enum-configs, it only checks the first, linked enum-config.
