This SHA512-certified bootable ISO provides the complete installation package for Cisco Unified Communications Manager (CUCM) v14.0.1, released on April 25, 2025 as part of Cisco’s Q2 collaboration suite update. Designed for enterprise-grade voice/video deployments, it combines the Unified Communications Operating System (UCOS) with pre-validated firmware bundles for Cisco UCS C-Series servers.

Key components include:

  • ​​Core CUCM Services​​: Call processing, SIP trunking, and device management
  • ​​Integrated Security​​: Preloaded TLS 1.3 certificates and FIPS 140-3 compliant encryption modules
  • ​​Platform Support​​: Optimized for Cisco UCS C240 M6/M7 rack servers and VMware ESXi 7.0U3+ hypervisors

2. Technical Enhancements & Security Updates

​​Infrastructure Optimization​​

  • 35% faster service profile initialization compared to CUCM 13.5
  • Unified SHA512 hashing for both OS image and embedded firmware packages
  • TLS 1.3 default encryption for all inter-node communication

​​Compliance Features​​

  • GDPR-ready call detail record (CDR) anonymization templates
  • Automated NTP chrony configuration aligned with MIL-STD-2105C standards

​​Resolved Vulnerabilities​​

  • Patched CVE-2025-12874 (XML external entity injection in serviceability API)
  • Mitigated CVE-2025-13182 (CLI privilege escalation via TACACS+)

​​Performance Benchmarks​​
