Introduction to CCP.1251.ES01.zip

The ​​CCP.1251.ES01.zip​​ is Cisco’s enhanced software package for enterprise collaboration infrastructure, released on March 12, 2025, as part of the Unified Communications Manager (UCM) 14.5 Extended Service (ES) series. Designed for organizations requiring FIPS 140-3 validated communication systems, this release focuses on hardening security protocols while maintaining backward compatibility with Cisco UCS C-Series servers and HyperFlex HX220c M6 nodes.

This version introduces Zero Trust Architecture (ZTA) principles for hybrid workforce environments, supporting encrypted video conferencing, persistent chat logging with AES-256-GCM encryption, and GDPR-compliant data retention policies. It serves as a critical update for enterprises managing Cisco Webex Calling hybrid deployments.
