This document provides instructions on how to configure ProSBC to interoperate with the TransNexus OSPrey server. OSPrey is a SIP redirect server that provides advanced Least Cost Routing (LCR), fraud control and STIR (Secure Telephony Identity Revisited) / SHAKEN (Secure Handling of Asserted information using toKENs) features.
ProSBC 3.0.90 or later version is needed to support secure caller ID using STIR/SHAKEN.
