​​Introduction to cm-locale-hu_HU-12.5.1.8000-1.cop.sha512​​

This Cisco Options Package (COP) provides Hungarian language localization with integrated SHA-512 checksum validation for Cisco Unified Communications Manager (CUCM) 12.5.x deployments. Released in Q3 2025, the package complies with Hungary’s National Media and Infocommunications Authority (NMHH) regulations, ensuring proper formatting of tax identifiers, emergency service numbers, and regional data protection standards. It supports bidirectional integration with Webex hybrid environments and Cisco Jabber endpoints, offering seamless language consistency across administrative interfaces, call detail records, and IP phone displays.

Designed for enterprises operating under Hungarian legal frameworks, the software is compatible with physical UCS C480 M5 servers and virtualized clusters running VMware ESXi 8.0 U2+ or HyperFlex 5.2. The SHA-512 cryptographic verification ensures file integrity during deployment, meeting FIPS 180-4 compliance requirements.
