Introduction to cm-locale-ru_RU-5.1.1.1-1.cop.sgn

This cryptographic localization package delivers full Russian (ru_RU) language support for Cisco Unified Communications Manager (CUCM) 5.1(1) systems operating under Eurasian Economic Union (EAEU) cybersecurity regulations. Released under Cisco’s Q4 2025 Legacy Software Maintenance Program (LSMP-UC-2025-12), it implements GOST R 34.11-2012 hash standards and complies with Roskomnadzor’s telecom infrastructure requirements.

The signed COP file requires 1.8GB disk space during deployment and supports CUCM clusters running base software 5.1(1).5000-2 or newer. Designed for enterprises maintaining GOST-compliant communication systems, it integrates with Cisco Smart Licensing v3.9 for compliance auditing through SHA-512 checksum validation.
