Introduction to CUC_14.0_v1.0.ova
This virtual appliance package provides a preconfigured deployment solution for Cisco Unified Communications Manager (CUCM) 14.0 environments, optimized for hybrid cloud implementations and enterprise-scale collaboration systems. As part of Cisco’s Q2 2025 software lifecycle refresh, the OVA template integrates FIPS 140-3 validated cryptographic modules and complies with NIST SP 800-193 platform resiliency guidelines.
The “_v1.0” designation indicates baseline feature parity with physical CUCM 14.0 installations, supporting core functions including SIP trunk management, device registration, and multi-cluster deployments. Released on March 15, 2025, this virtualization-ready package reduces deployment time by 65% compared to manual configurations.

End-of-Support Notice
CUCM 13.5 virtual appliances will reach end-of-life on December 31, 2026. Transition to 14.0 virtualized deployments is required to maintain compliance with FIPS 140-3 cryptographic standards.
This package aligns with Cisco’s 2025 Virtualization Security Framework and implements NIST SP 800-207 zero trust architecture principles for enterprise collaboration environments.
