Introduction to cm-locale-et_EE-12.5.1.7000-1.cop.sha512

This cryptographic locale package delivers specialized Estonian language support for Cisco Unified Communications Manager (CUCM) 12.5(1) systems, optimized for compliance with Estonia’s Information System Authority (RIA) technical standards. Released in Q4 2025, it implements Unicode 16.0 Baltic script rendering rules and updates timezone configurations per Estonia’s 2025 daylight saving time legislation.

The software maintains compatibility with Cisco UCS C-Series servers (C220/C240 M7) and virtualized environments using VMware ESXi 8.0 U4+ or KVM 7.0+ hypervisors. It resolves 11 localization issues identified in previous CUCM versions, including Northern/Eastern Estonian dialect support for automated call routing systems and ISO 8601-1:2024 date format compliance.
