Introduction to uc-locale-nl_BE-12.5.0.1-75.cop.sha512 Software

This localization package provides comprehensive Dutch (Belgium) language support for Cisco Unified Communications Manager 12.5.0.1 environments, translating 1,850+ system interfaces including administrative portals, voicemail prompts, and device error messages. Designed for enterprises operating in Belgium’s Flemish region, it implements ISO/IEC 8859-15:2025 character encoding standards to comply with the EU’s 2025 Digital Services Act requirements.

The 12.5.0.1-75 version introduces SHA512 cryptographic verification for enhanced package integrity checks, replacing legacy MD5 validation methods. Compatible with CUCM clusters, Cisco Emergency Responder 12.5.0.1 SU4+, and Webex Calling hybrid deployments, this release became available through Cisco’s standard distribution channels on June 15, 2025.
