            Note
            title Use of Local Pass-through Authorization Table is Strongly Recommended
            Ribbon and Yealink strongly recommend the use of the optional Local Passthrough Authorization Table, especially for Azure-based SBC deployments. The use of the Local Passthrough Authorization Table deters the fraudulent use of your enterprise's SIP trunking services by unauthorized users.

            title Use of Signaling and Media Encryption Strongly Recommended for Azure-based SBC Deployments
            While optional, Ribbon Communications and Yealink strongly recommend the use of TLS and SRTP for secure encrypted communication between the Yealink devices and the SBC, especially when the latter is deployed in the Azure public cloud. For more information, please refer above.
