Introduction to cucm_im_p_9.0_vmv7_v1.0.ova

This 18.4GB Open Virtual Appliance (release date: Q1 2025) provides a preconfigured VMware template for deploying Cisco Unified Communications Manager (CUCM) 9.0 in virtualized environments. Designed for enterprises requiring FIPS 140-3 compliant collaboration infrastructure, it implements optimized resource allocation for 5,000+ device deployments with 30% faster VM startup compared to manual configurations.

The OVA template integrates with Cisco HyperFlex 5.0+ and vSphere 8.0 clusters, supporting both on-premises deployments and Webex Hybrid implementations. It includes pre-aligned disk partitions for SAN storage systems, ensuring TAC-supported performance levels.
