Introduction to cue-vm-k9.SPA.sme.8.6.4.zip
This OVA deployment package delivers Cisco Unity Express 8.6.4 virtual appliance optimized for SME UC deployments requiring voicemail, auto-attendant, and IVR solutions. Designed for virtualized Cisco Unified Communications Manager environments, it integrates with CUCM 12.5(1)SU6 and later through SIP trunking while maintaining backward compatibility with legacy CUE hardware platforms.
The 8.6.4 build introduces FIPS 140-2 Level 1 compliance for government/military deployments and resolves 12 critical CVEs identified in previous versions. Released Q3 2024, this version aligns with Cisco’s Secure Unified Communications Framework, requiring SHA-512 verification during installation to prevent tampering.
Key Features and Enhancements
1. Security Hardening
- Implements TLS 1.3 for all SIP/SRTP signaling channels
- 256-bit AES-GCM encryption for voicemail storage
- Automated certificate rotation every 90 days (FIPS mode)
2. Performance Optimizations
- 40% faster voicemail indexing through Elasticsearch 7.17 integration
- Support for 2,000 concurrent IVR sessions (vs 1,500 in 8.5.x)
- Reduced VM resource footprint: 8vCPU/16GB RAM baseline (from 12vCPU/24GB)
3. Multi-Tenancy Improvements
- Tenant-specific TLS certificate management
- Resource quota enforcement per organizational unit
- Isolated LDAP directories for partitioned deployments
