Introduction to cm-locale-de_DE-12.5.1.5000-1.cop.sgn

This digitally signed Cisco Options Package (COP) delivers comprehensive German language support for ​​Cisco Unified Communications Manager (CUCM) 12.5.1​​, enabling GDPR-compliant voice collaboration systems in DACH-region enterprises. Officially released on February 10, 2025, the package implements ISO 8601-1:2024 date formats, DIN 5008-compliant text encoding, and locale-specific security protocols required for German telecommunications regulations.

Compatible with CUCM clusters deployed on Cisco UCS C220/C240 M7 servers, the localization pack supports hybrid deployments integrating Webex Calling and on-premises IP telephony. It addresses critical compliance requirements from Bundesnetzagentur (BNetzA) for emergency service routing and call detail record (CDR) formatting.
