Explanation

On Cisco Expressway, the SIP-H.323 interworking setting of 'On' allows the Expressway to perform protocol translation between SIP and H.323 for any call, regardless of whether an endpoint is registered. 'Registered Only' restricts interworking to calls involving at least one registered endpoint, which would not cover the scenario where no endpoint is registered locally. 'Off' disables interworking entirely. 'Enabled' is not a valid option for this setting. When acting as a gateway for protocol interworking with no local registrations (e.g., for transit B2B calls), 'On' is the required setting.
