Endpoint Demotion due to CAC overage

The Oracle® Enterprise Session Border Controller can demote endpoints from trusted to untrusted queues when CAC failures exceed a configured threshold. The Oracle® Enterprise Session Border Controller can also demote endpoints from untrusted to denied queues when CAC failures exceed a another configured threshold.

The Oracle® Enterprise Session Border Controller maintains CAC failures per-endpoint. The CAC failure counter is incremented upon certain admission control failures only if either one of cac-failure-threshold or untrust-cac-fail-threshold is non-zero.

The cac failure threshold parameter is available in the access control and realm configuration elements. Exceeding this parameter demotes an endpoint from the trusted queue to the untrusted queue. The untrust cac-failure-threshold parameter is available in the access control and realm configuration elements. Exceeding this parameter demotes an endpoint from the untrusted queue to the denied queue.

If both the cac failure threshold and untrusted cac failure threshold are configured to 0, then admission control failures are considered and counted as invalid signaling messages for determining if the invalid-signal-threshold parameter value has been exceeded.
