Introduction to UCSInstall_CUP_UNRST_11.5.1.23900-3.sha512.iso
This ISO package contains the Unrestricted Security Version of Cisco Unified Presence Server (CUP) 11.5.1 Maintenance Release, specifically designed for organizations requiring FIPS 140-2 validated cryptography modules. Released on April 15, 2025, this build (23900-3) addresses critical vulnerabilities in XMPP federation services while maintaining backward compatibility with Cisco Unified Communications Manager 11.5(1) SU3+ deployments.
The “UNRST” designation indicates support for non-FIPS operational modes, allowing transitional security configurations during hybrid cloud migrations. Administrators can manage up to 50,000 concurrent Jabber/XMPP endpoints through this release’s enhanced monitoring dashboard.
Key Features and Improvements
1. Cryptographic Framework Updates
- FIPS 140-2 Level 1 compliance with OpenSSL 3.0.11 integration
- TLS 1.3 enforcement for all SIP/XMPP federation connections
2. Protocol Enhancements
- 30% faster XMPP message routing via optimized SASL authentication pipeline
- SIP OPTIONS ping reduction for improved CUCM cluster stability
3. Administrative Controls
- Granular certificate management with OCSP stapling support
- Real-time encryption status indicators in serviceability dashboards
4. Virtualization Optimizations
- VMware vSphere 8.0U2 compatibility with NVMe datastore support
- Resource allocation templates for Cisco UCS C220 M7 servers
