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

This Cisco-signed localization package provides native German language support (locale identifier: de_DE) for Cisco Unified Communications Manager (CUCM) 12.5(1)SU6 systems. Designed for enterprises operating in German-speaking regions, it enables full translation of administrative interfaces, error messages, and system logs while ensuring compliance with EU language regulations.

The 12.5.1.6000-1 version introduces UTF-8 character encoding optimizations for German umlauts (ä, ö, ü) and sharp S (ß), resolving display inconsistencies reported in previous releases. Compatible with CUCM clusters running 12.5(1)SU2 or later firmware, it supports both on-premises and Cisco-hosted hybrid deployments.
