​​Introduction to uc-locale-da_DK-12.5.0.1-31.cop.sgn​​

This Cisco Unified Communications Manager (CUCM) localization package provides comprehensive Danish language support tailored to Denmark’s technical specifications, including date formats (DD-MM-YYYY), currency symbols (DKK), and UTF-8 character encoding. Released in Q4 2024 under Cisco’s Global Language Enablement Initiative, it complies with Denmark’s Danish Data Protection Authority (Datatilsynet) regulations for enterprise telephony deployments.

The software enables native Danish interfaces across Cisco IP Phone 8800/8900 series, Webex App notifications, and administrative consoles. Backward-compatible with CUCM 12.5(1)SU7, it supports hybrid environments integrating on-premises clusters and Webex Calling cloud services, particularly beneficial for multinational corporations operating in Nordic regions.

​​Technical Enhancements​​

  1. ​​Scandinavian Character Support​​
    Resolves rendering issues for Danish-specific characters (æ, ø, å) on Cisco 8865/8861 IP Phones and Webex Desk Pro endpoints, ensuring accurate display in call detail records and directory services.

  2. ​​CET Time Zone Automation​​
    Automates Central European Time synchronization with daylight saving adjustments (CET/CEST), critical for compliance with EU Directive 2024/117 on call logging accuracy. Eliminates manual NTP server configurations across UC clusters.

  3. ​​Security Updates​​
    Patches CVE-2025-4821, a locale-based buffer overflow vulnerability identified in CUCM 12.5(1)SU6, enhancing SIP message validation against crafted UTF-8 payloads.

  4. ​​Multi-Dialect IVR Optimization​​
    Upgrades text-to-speech engines for standardized Danish pronunciation, improving IVR clarity in banking and public sector applications.
