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

The ​​ps-locale-de_DE-12.5.1.6000-1.cop.sgn​​ is an official Cisco localization package enabling German (Germany) language support for Cisco Unified Communications Manager (CUCM) 12.5.1 systems. Released on October 15, 2025, this COP file implements ISO 639-1:2023-compliant translations for administrative interfaces, device configurations, and API responses, tailored to Germany’s regional standards. Designed for enterprises operating in German-speaking markets, it addresses compliance requirements under Germany’s Federal Network Agency (BNetzA) for localized telecommunications systems.

This language pack supports hybrid deployments integrating on-premises CUCM clusters with Webex Calling services, ensuring consistent UI translations for Cisco IP Phone 8800 Series endpoints and Webex App users.
