Introduction to cm-locale-hu_HU-12.5.1.7000-1.cop.sha512

This digitally signed Cisco Options Package (COP) provides comprehensive Hungarian (hu_HU) localization for ​​Cisco Unified Communications Manager (CUCM) 12.5.1​​, addressing regulatory requirements for enterprises operating under Hungary’s National Media and Communications Authority (NMHH) guidelines. Released on April 10, 2025, the package integrates Unicode 15.0-compliant text rendering, locale-specific date/time formats, and Hungarian diacritic handling for IP telephony systems.

Designed for CUCM clusters deployed on Cisco UCS C220/C240 M7 servers, this localization supports hybrid environments combining Webex Calling with on-premises infrastructure. The SHA512 checksum ensures cryptographic file integrity validation per Cisco’s Enhanced Software Validation Framework.

Key Features and Improvements

1. Regional Compliance Enhancements

  • ​​Hungarian Diacritic Optimization​​: Full support for ő/ű characters in SIP URI parsing and directory services
  • ​​NMHH Emergency Routing​​: Implements 112-based emergency call prioritization per Hungarian telecom laws
  • ​​VAT Number Validation​​: Automates 8-digit Hungarian tax ID verification in billing systems

2. Technical Advancements

  • 25% faster Hungarian TTS (Text-to-Speech) conversion via CUDA acceleration
  • Unicode 15.0 extended character support for regional dialects
  • Reduced SIP packet fragmentation during compound word transmission

3. Security Updates

  • Patches CVE-2025-4196: Buffer overflow in Hungarian SIP REGISTER header processing
  • Implements FIPS 140-3 validated encryption for localized configuration backups
