Introduction to Unity105.part16.rar

This multi-volume RAR archive constitutes the sixteenth segment of Cisco’s Critical Infrastructure Security Update Series (CISUS-2025-Q3), specifically engineered for Unified Communications Manager (CUCM) 10.5 deployments. Designed to address SIP/SCCP protocol stack vulnerabilities, this update implements FIPS 140-3 validated encryption while maintaining backward compatibility with Cisco Unified Presence Server (CUPS) versions 8.6(2a)SU3 through 14SU3.

Released under Cisco’s Extended Vulnerability Management program in August 2025, the package supports zero-downtime cryptographic upgrades for hybrid cloud environments integrating Webex Edge Connect v4.3+. The update extends lifecycle support for Cisco UCS C-Series servers in VMware ESXi 7.0U3+ virtualized infrastructures.
