Introduction to CUCSRSV_14.0_v1.2.ova

This OVA template provides the Survivable Remote Site Voicemail (SRSV) solution for Cisco Unity Connection 14.0 deployments, designed to maintain voice messaging continuity during WAN outages at branch locations. Released on April 25, 2025, it integrates with Cisco Unified Communications Manager (CUCM) to ensure uninterrupted voicemail services for up to 500 users per remote site. The SHA-512 cryptographic verification ensures file integrity for secure virtualization platform deployment.

Key Features and Improvements

    • Supports 35 concurrent branch deployments per centralized Unity Connection server cluster

  2. ​​Security Enhancements​​

    • Addresses CVE-2015-0235 (GHOST vulnerability) through glibc library updates
    • Implements FIPS 140-3 validated encryption for voicemail data synchronization

  3. ​​Performance Optimization​​

    • Reduces voicemail replication latency by 40% compared to v11.x implementations
    • Supports VMware vSphere 8.0 U2 virtualization environments with NVMe storage acceleration

  4. ​​Protocol Support​​

    • Enhanced SIP/TLS 1.3 integration for secure inter-cluster communication
    • Compatibility with Cisco Expressway X12.5.9 traversal zones for hybrid deployments
