Introduction to CCE901_Beta2.zip Software
The CCE901_Beta2.zip represents Cisco’s next-generation session management solution for hybrid collaboration infrastructure, designed to enhance secure SIP trunking and WebRTC connectivity in CUCM 15.2+ environments. Released on April 30, 2025, this 289.7 MB firmware package introduces experimental support for quantum-resistant encryption protocols while maintaining backward compatibility with existing Expressway E14.2.x deployments.
This beta release targets enterprise networks requiring RFC 9143-compliant STIR/SHAKEN call authentication and enhanced DoS protection for Microsoft Teams Direct Routing integrations. It serves as a critical test platform for validating AI-driven traffic anomaly detection algorithms in multi-vendor UCaaS environments.
