High Availability (HA) Support

An Oracle® Enterprise Session Border Controller using SIPREC supports HA in the network. The Oracle® Enterprise Session Border Controller replicates all metadata states between the active and standby Oracle® Enterprise Session Border Controllers. Any recording dialogs in progress do not survive the failover, but all calls in progress are preserved. Additionally, the recording dialogs are replicated as well to the failed over Oracle® Enterprise Session Border Controller so that in-dialog SIP requests continue to function.

Each recorded communication session replicated to a single SRS counts as two calls instead of one. The Oracle® Enterprise Session Border Controller creates two flows between the two participants and two additional flows to the SRS for each of the parent flows.
