The event validated GSMA VoLTE recommendations for UE-to-Core Network interoperability in a multi-vendor deployment across host sites in Beijing and Kranj. Test scenarios covered RCS VoLTE within single networks and for roaming, utilizing interconnected IPX links and DIAMETER Routing Agents to simplify message routing. Participants demonstrated successful voice and video calls with appropriate quality of service, alongside multimedia telephony services and RCS service configurations. The results were documented in a white paper available from ETSI, highlighting the successful interoperability of UEs, network infrastructure, and services from multiple vendors.
