​​Introduction to cm-locale-et_EE-11.5.1.10000-1.cop.sgn​​

cm-locale-et_EE-11.5.1.10000-1.cop.sgn is a critical localization package for Cisco Unified Communications Manager (CUCM) 11.5 Service Update 1 deployments requiring Estonian language support. Released in Q3 2024 under Cisco’s Global Language Compliance Initiative, this COP file enables complete localization of CUCM administrative interfaces, user portals, and system-generated notifications in Estonian (et_EE).

The package aligns with European Union Language Standard EN 15038:2025, providing accurate translations for over 18,000 UI elements across CUCM’s call routing, device management, and reporting modules. It maintains compatibility with existing CUCM 11.5(1)SU1 clusters while supporting regional requirements for date/time formats (ISO 8601:2024) and numeric representations.
