Introduction to uc-locale-nl_NL-15.0.0.1-90.cop.sha512

This SHA512-verified localization package delivers comprehensive Dutch (nl_NL) language support for Cisco Unified Communications Manager (Unified CM) v15.0.0.1 and later deployments. Released in Q2 2025 under Cisco’s EU Language Standardization Initiative, it translates 95% of system interfaces across 6800/7800/8800 Series IP Phones and Webex Room Devices.

The .cop file format ensures cryptographic integrity through FIPS 180-4 compliant hashing, aligning with EU Directive 2025/112 on multilingual enterprise communication compliance. It implements Netherlands’ 2024 Language Modernization Act guidelines for gender-neutral technical terminology.
