1. Introduction to CUCM_7500_user_v1.0_vmv7.ova

This OVA template enables rapid deployment of Cisco Unified Communications Manager (CUCM) 14.5 on UCS 7500 Series hardware, specifically optimized for large-scale enterprise voice/video collaboration environments. Designed under Cisco’s Virtualization Experience Media (VXM) 7 framework, the template pre-configures resource allocation for 50,000+ IP phone endpoints while maintaining PCI-DSS compliance for contact center deployments.

Certified for use with Cisco UCS C480 M6 rack servers and Intersight managed infrastructure, this virtualization package supports multi-cluster configurations with automatic service profile synchronization. The v1.0_vmv7 build received Cisco’s Technical Approval (TAC Case 7544332) on March 15, 2025, addressing critical vulnerabilities identified in CSCwi93485 security advisory.
