Introduction to CUCSRSV_14.0_v1.2.ova

This Open Virtual Appliance (OVA) file deploys Cisco’s Survivable Remote Site Voicemail (SRSV) solution, designed to maintain voicemail services at branch locations during WAN outages. Compatible with Cisco Unified Communications Manager (CUCM) 14.x environments, the virtual appliance ensures business continuity by caching up to 500 user mailboxes locally when connectivity to central Unity Connection servers is disrupted.

Released in Q2 2025 as part of Cisco’s enterprise collaboration resilience roadmap, version 14.0_v1.2 introduces enhanced synchronization protocols and security hardening aligned with NIST SP 800-193 guidelines for persistent storage protection.
