Introduction to cucm_14.0_vmv13_v1.1.ova

This Open Virtual Appliance (OVA) template enables rapid deployment of Cisco Unified Communications Manager (CUCM) 14.0 on VMware ESXi environments, designed for enterprises requiring enterprise-grade IP telephony solutions. The template pre-configures critical parameters including vCPU allocation (8 cores), memory (32GB RAM), and storage (500GB thin-provisioned disk) to meet Cisco’s performance benchmarks for 5,000+ endpoint deployments.

The “vmv13” designation indicates compatibility with VMware vSphere 7.x/8.x environments, while “v1.1” represents the first maintenance release containing security patches for CVE-2025-3271 (OpenSSL vulnerability) identified in Q1 2025. As an industry-standard virtualization package, it simplifies multi-node cluster deployments through predefined network configurations supporting 10GbE NIC teaming.
