1. Introduction to CUE-Virtual-10.0.1.ova

This preconfigured virtual appliance delivers enterprise-grade collaboration capabilities for Cisco Webex Calling and Unified Communications Manager (CUCM) 14.5+ deployments. Designed under Cisco’s Virtualization First strategy, it consolidates voicemail, auto-attendant, and presence services into a single OVA template optimized for hybrid cloud architectures.

Validated for VMware ESXi 8.0U2 and KVM 4.5+ hypervisors, the package supports up to 5,000 concurrent voice sessions with 99.999% service availability guarantees. Officially released on March 18, 2025 through Cisco’s Collaboration Software Repository, version 10.0.1 introduces AI-driven call routing optimization and hardware security module (HSM) integration.

2. Key Features and Improvements
