Introduction to uc-locale-da_DK-12.5.0.1-54.cop.sha512

This Cisco OS Package (COP) provides Danish (da_DK) localization support for Unified Communications Manager 12.5 environments. Designed to meet Denmark’s regional compliance requirements, it adapts administrative interfaces, system prompts, and error messages to align with Danish language standards and cultural conventions. The “.sha512” extension confirms cryptographic integrity verification through SHA-512 hashing, ensuring secure software validation.

Released on April 28, 2025, as part of Cisco’s Q2 localization updates, version 12.5.0.1-54 addresses requirements from Denmark’s 2024 Data Protection Amendment Act. Compatible systems include CUCM clusters running 12.5(1)SU3 or later, with mandatory Red Hat Enterprise Linux 8.6 OS support.
