Introduction to li-ffr.4-0-1-RUS.exe

This SHA512-authenticated software package delivers Russian language localization for Cisco Unified Communications Manager (CUCM) v14.x environments. Designed to meet Eurasian Economic Union (EEU) technical regulations (TR CU 004/2023), it provides Cyrillic script support for 95% of administrative interfaces and 90% of endpoint portals across Cisco collaboration ecosystems.

Released under Cisco’s Q2 2025 software maintenance cycle (version 4.0.1-RUS), this update implements GOST R 34.11-2023 cryptographic standards required for Russian Federation government deployments. Compatible with CUCM clusters running 14.0(2)SU2+, it introduces optimizations for Cisco Webex Room Kit Pro endpoints with enhanced right-to-left text rendering capabilities.
