Q.850 Cause to H.323 Release Complete Reason

When a call that requires the IWF terminates from the H.323 side and no H.323 Release Complete Reason is specified, the Oracle® Enterprise Session Border Controller maps the Q.850 cause to an H.323 Release Complete Reason using the mapping scheme in the following table. This new H.323 status is then mapped to a SIP status as described in the IWF Termination from SIP table.
