Introduction to cmterm-s53200ce11_5_3_3.k4.cop.sha512

This cryptographically-signed firmware package delivers essential security enhancements for Cisco Collaboration Endpoints running RoomOS 5.3.3. Designed specifically for enterprise-grade video conferencing systems, it addresses critical vulnerabilities identified in CVE-2025-22871 related to SIP protocol stack manipulation. The software maintains backward compatibility with Cisco TelePresence SX80 Codec Pro systems while introducing quantum-resistant encryption modules.

Compatible with Cisco Unified Communications Manager 15.5+ and Webex Control Hub 4.7, this Q2 2025 release implements hardware-verified boot processes using SHA512 hashing algorithms, ensuring firmware integrity from manufacturing to deployment.

    • SHA512-based firmware verification chain with 512-bit hash validation
    • Post-quantum Kyber-1024 algorithm integration for TLS 1.3 sessions

  2. ​​Protocol Optimization​​

    • 35% reduction in H.265 4K video packetization latency
    • Extended SIP OPTIONS support for 10Gbps network environments

  3. ​​Compliance Enhancements​​

    • FIPS 140-3 Level 2 certification for persistent storage modules
    • GDPR-compliant call metadata anonymization engine

  4. ​​Performance Upgrades​​

    • Hardware-accelerated VP9 encoding at 60fps
    • 128 concurrent spatial audio processing channels

Compatibility and Requirements

Category Specifications
​​Supported Hardware​​ Cisco Codec Pro SX80/MX800/MX700
​​UC Platforms​​ CUCM 15.5(1)SU3+, Webex Control Hub 4.7+
