Introduction to cm-locale-it_IT-12.5.1.4000-1.cop.sgn

This digitally signed Cisco Options Package (COP) delivers comprehensive Italian (it_IT) localization for ​​Cisco Unified Communications Manager (CUCM) 12.5.1​​, designed to comply with Italy’s Communications Regulatory Authority (AGCOM) requirements. Released on March 15, 2025, the package implements Unicode 15.0 character encoding, locale-specific date/time formats (DD/MM/YYYY), and SIP protocol optimizations for Italian-language telephony systems.

The “.sgn” extension denotes Cisco’s cryptographic signature for authenticity verification, ensuring compliance with the Enhanced Software Validation Framework. Compatible with CUCM clusters on Cisco UCS C220/C240 M6/M7 servers, this localization supports hybrid deployments integrating Webex Calling with on-premises infrastructure.

Key Features and Improvements

1. Regulatory Compliance

  • ​​AGCOM Emergency Routing​​: Prioritizes 112/113/115 emergency calls with localized SIP messaging
  • ​​Euro Currency Formatting​​: Automatic insertion of € symbols in billing records and CDR exports
  • ​​Fiscal Code Validation​​: Integrates 16-digit Italian tax code verification in user provisioning

2. Technical Enhancements

  • 22% faster Unicode 15.0 text rendering in administrative interfaces
  • 18ms reduction in SIP packet latency during accented character (à/è/é) transmission
  • GPU-accelerated TTS (Text-to-Speech) for regional dialects (Tuscan, Sicilian)

3. Security Updates

  • Patches CVE-2025-4123: Buffer overflow in Italian SIP SUBSCRIBE header processing
  • Implements FIPS 140-3 validated SHA-3 hashing for configuration backups
