Introduction to UCSInstall_UCOS_14.0.1.10000-20.sha512.iso

This SHA512-verified ISO image serves as the foundational installation package for Cisco Unified Communications Manager (CUCM) 14.0.1 and associated collaboration services. Designed for enterprise-grade UC deployments, it contains the Unified Communications Operating System (UCOS) – Cisco’s Linux-based platform optimized for real-time voice/video processing.

The “14.0.1.10000-20” version identifier confirms compatibility with Cisco’s 2025 Q1 security patches and Webex ecosystem integrations. As a bootable image, it supports bare-metal installations on UCS C-Series servers and virtualization platforms like VMware ESXi 8.0.

​​Core Specifications​​

  • ​​Release Version:​​ 14.0.1.10000-20 (Feature Update 20)
  • ​​Build Date:​​ March 15, 2025
  • ​​File Integrity:​​ FIPS 180-4 compliant SHA512 checksum

Key Technical Enhancements

  1. ​​Security Architecture​​
    Implements TLS 1.3 endpoint encryption by default and removes deprecated SSLv3 handshake protocols, aligning with NIST SP 800-52 Rev. 3 standards.

  2. ​​Webex Native Integration​​

    • Pre-installed Webex Edge for Cloud-Connected PSTN
    • AI-driven meeting join optimizations (25% faster room entry vs. CUCM 12.x)

  3. ​​Performance Upgrades​​

    • 40% reduction in DTMF processing latency
    • Support for 10,000 concurrent SIP sessions per node

  4. ​​Automated Deployment​​
    Embedded Cisco UCS Director 8.0 templates enable zero-touch provisioning of UCS C220 M6/C240 M6 hardware clusters.

Compatibility Matrix

​​Component​​ ​​Supported Versions​​
Cisco UCS Hardware C220 M6, C240 M6, C480 ML
Hypervisor Platforms ESXi 8.0, KVM 5.12, Hyper-V 2025
