1. Introduction to ps-locale-ru_RU-12.5.1.6000-1.cop.sgn

This cryptographic signature file authenticates the Russian language localization module for Cisco’s enterprise collaboration platforms. Designed to meet EAEU Technical Regulation TR CU 032/2024 requirements, it provides full Cyrillic UI translation for Cisco Unified Communications Manager 12.5.1 deployments. The .sgn file serves as a digital certificate ensuring the integrity of associated .cop installation archives, critical for compliance with Russian Federation data sovereignty regulations.

Compatibility extends to:

  • Unified Communications Manager 12.5(1)SU4 through 12.5(3)
  • IM and Presence Service 12.5(1)ES6
  • Webex Hybrid Services with on-premises control

Release Date: January 2025 (Q1 maintenance cycle)
