Introduction to cm-locale-ru_RU-4.1.3.4000.exe

This SHA512-validated localization package delivers comprehensive Russian language support for Cisco Unified Communications Manager (Unified CM) 4.1.x environments. Designed for CIS-region deployments, it enables full Cyrillic character rendering across administrative interfaces, IP phone displays (8800/8900 Series), and Webex App endpoints.

Released under Cisco’s Q3 2025 maintenance cycle, the 4.1.3.4000 build implements GOST R 58148-2018 standards for enterprise communications localization. The package contains 2,800+ translated system prompts and menu items while maintaining backward compatibility with legacy SIP devices in hybrid UC environments.
