Introduction to cucm_9.1_vmv8_v1.5.ova Software

This VMware-optimized OVA template (4.7GB) provides a preconfigured virtualization package for deploying Cisco Unified Communications Manager (CUCM) version 9.1 on VMware vSphere 8 environments. Released under Cisco’s Enhanced Software Maintenance program in Q3 2023, it enables rapid deployment of enterprise-grade VoIP infrastructure supporting up to 15,000 registered devices per cluster.

Designed for hybrid cloud environments, the template integrates with Cisco Unified Computing System (UCS) C-Series servers and complies with NIST SP 800-193 firmware resilience standards. It supports multi-tenancy configurations through Cisco Unified CM Session Management Edition (SME) 14.5+ integration.
