Introduction to UCCX100.part12.rar

This multi-volume RAR archive forms part of Cisco’s Critical Infrastructure Security Update Series (CISUS-2025-Q3), specifically addressing vulnerabilities in Unified Contact Center Express (UCCX) 10.5 deployments. As the twelfth segment of the UCCX100 patch sequence, this update implements FIPS 140-3 compliance for government-grade contact center operations and integrates with Cisco Unified Communications Manager (CUCM) versions 12.5(1)SU6 through 14SU3.

Released under Cisco’s Extended Security Maintenance program in July 2025, the package enables zero-downtime cryptographic upgrades for mission-critical call routing infrastructures. It supports hybrid deployments integrating Webex Contact Center v4.3+ and Cisco Finesse browser-based agent desktop environments.
