H.225

When in H.225 proxy mode, the Oracle® Enterprise Session Border Controller only proxies call signaling (H.225 messages). The call control (H.245 messages) and the media associated with the session do not go through the Oracle® Enterprise Session Border Controller. Instead, they flow directly between the two H.323 endpoints.

Note:

H.225 proxy mode is only used in specific applications and should not be enabled without consultation from your Acme Packet Systems Engineer.

The following diagram shows the flow.

In certain deployments, the call control message and media are exchanged between the two H.323 endpoints themselves. When the Oracle® Enterprise Session Border Controller is in H.225 proxy mode, any tunneled H.245 message on the ingress side is tunneled in the egress side; this is irrespective of the value configured in the value you set for the h.245-tunneling parameter in the H.323 stack configuration.
