Introduction to uc-locale-de_DE-12.5.0.1-75.cop.sha512

This localization package delivers ISO 639/3166-compliant German (de_DE) language support for Cisco Unified Communications Manager (CUCM) 12.5.0.1 deployments. Designed for DACH region (Germany, Austria, Switzerland) compliance, it implements German-specific formatting rules including date displays (DD.MM.YYYY), numeric separators (comma decimal), and extended umlaut character support across collaboration endpoints.

Released under Cisco’s Q1 2025 software maintenance cycle, the package incorporates SHA-512 cryptographic validation for secure deployment. Compatible with CUCM 12.5.0.1 SU5 and later versions, it resolves localization inconsistencies reported in previous iterations for German-speaking markets.
