          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.
