Introduction to ps-locale-nl_NL-12.5.1.7000-1.cop.sha512

The ​​ps-locale-nl_NL-12.5.1.7000-1.cop.sha512​​ is a cryptographic-verified localization package for Cisco Collaboration systems, providing full Dutch language support compliant with EU language standards (ISO 639-1 “nl”) and Netherlands-specific regulations. Designed for Cisco Unified Communications Manager (CUCM) 12.5.1 and later, this software ensures precise handling of Dutch diacritical characters (ë/ï/é), EUR currency formatting (€), and date conventions (DD-MM-YYYY) per NEN-EN 28601 standards.

Key functionalities include:

  • Complete translation of administrative interfaces across Cisco Webex Control Hub
  • 21% VAT compliance for billing modules in Euro currency
  • SHA-512 hashing for end-to-end software integrity verification
  • Dual-language fallback system (Dutch/English)

Released in Q4 2025, version 12.5.1.7000 introduces expanded Unicode 16.0 support for Caribbean Netherlands (BES islands) dialect terminology.
