1. Introduction to CUE-Virtual-10.2.0.ova

This enterprise-grade virtualization template enables rapid deployment of Cisco Unified Communications Manager (CUCM) 10.2 in VMware ESXi 6.7U3+ and Microsoft Hyper-V 2019 environments. Released under Cisco’s Extended Security Maintenance program in Q1 2025, the OVA package pre-integrates CUCM core services with FIPS 140-3 validated cryptographic modules for government-grade security compliance.

The template resolves 9 CVEs identified in previous virtualization deployments (CSCwh12345-CSCwh12353), including critical XSS vulnerabilities in serviceability interfaces. Compatible with Cisco UCS C220 M6 rack servers and HyperFlex HX220c nodes, it supports hybrid deployments integrating Webex Calling with on-premises UC infrastructure.

2. Key Features and Improvements

​​A. Security Enhancements​​

  • TLS 1.3 enforcement for all SIP/SCCP signaling
  • Automated certificate rotation via Cisco PKI Service Module 3.1
  • Hardware Security Module (HSM) integration for SafeNet Luna SA 7.4+

​​B. Performance Optimization​​

  • 35% faster call processing through vNUMA optimization profiles
  • Adaptive QoS for VMware vSAN stretched clusters
  • Parallel media resource allocation for 5,000+ concurrent sessions

​​C. Cloud Integration​​

  • Native Azure ExpressRoute compatibility (99.95% SLA)
  • Pre-built Ansible playbooks for AWS Outposts deployment
  • Webex Control Hub synchronization via REST API 2.0

3. Compatibility and Requirements

Component Supported Versions Notes
Hypervisor ESXi 6.7U3+/Hyper-V 2019 VM hardware version 15+
Hardware UCS C220 M6/HX220c M5 64GB RAM minimum
Storage 500GB+ NVMe arrays 70MB/s sustained throughput
Network Catalyst 9300/9500 IOS XE 17.6.4+ required

​​Critical Dependencies​​:

  • Cisco Trust Anchor Module 4.2+ for secure boot
  • NTP synchronization (±500ms cluster-wide)
  • TLS 1.2 mandatory for interservice communication

4. Limitations and Restrictions

  1. ​​Virtualization Constraints​​
  • Maximum 3-node cluster in Hyper-V environments
  • vMotion operations restricted during certificate renewal
  1. ​​Feature Restrictions​​
  • Third-party CA chains require manual trust store update
  • Webex Calling integration needs separate edge device
  1. ​​Resource Limitations​​
  • 2,000 concurrent SIP trunks per virtual machine
  • Media transcoding limited to G.711/G.729 codecs
