​​1. Introduction to PCD_UCOS_14.0.1.11900-136.sha512.iso Software​​

This ISO image contains Cisco’s Unified Communications Operating System (UCOS) version 14.0.1, designed for enterprise-grade collaboration infrastructure. Released on March 28, 2025, under Cisco’s Q2 software maintenance cycle, it provides critical updates for Unified Communications Manager (UCM) clusters and Webex Calling hybrid deployments. The SHA-512 hash verification ensures cryptographic integrity for compliance with NIST SP 800-207 zero-trust standards.

Core functionalities include:

  • Multi-tenant call processing with ISO 8601:2024 timezone management
  • TLS 1.3 encrypted SIP trunking support
  • Enhanced JTAPI security certificate handling

​​2. Key Features and Improvements​​

​​Protocol Enhancements​​

  • Native support for RFC 8866 SDP security descriptions
  • DTLS 1.3 acceleration for WebRTC endpoints (30% faster handshake)
  • FIPS 140-3 validated cryptographic modules

​​Performance Optimization​​

  • 40% faster cluster database synchronization
  • NUMA-aware memory allocation for Cisco UCS C-Series servers
  • Resolved CSCwd15301 memory leak in multi-tenant environments

​​Security Architecture​​

  • Automated SHA-512 checksum validation during installation
  • OCSP stapling for X.509 certificate revocation checks
  • Hardware Security Module (HSM) integration for JTAPI keys

​​3. Compatibility and Requirements​​

​​Component​​ ​​Supported Versions​​ ​​Technical Specifications​​
