​​Introduction to uc-locale-en_GB-15.0.0.1-90.cop.sha512​​

This cryptographic hash-verified localization package enables British English language support for Cisco Unified Communications Manager (CUCM) 15.0 SU1 and compatible collaboration endpoints. Designed for enterprises requiring UK-specific locale configurations, it implements ISO 8601 date/time formats (£ currency symbol), GB18030 character encoding standards, and regional telephony protocols.

As part of Cisco’s Q4 2024 software update cycle, the package integrates SHA-512 checksum validation (FIPS 180-4 compliant) to ensure file integrity during deployment. It supports multilingual UC environments where British English localization must coexist with other language packs under centralized CUCM administration.

​​Key Features and Improvements​​

  1. ​​Regional Compliance Enhancements​​

    • Implements £ currency formatting with 3-digit grouping (e.g., £1,000.00 instead of €1.000,00)
    • Supports UK-specific emergency service number mapping (999/112) in CUCM dial plans
    • Resolves daylight saving time (BST) synchronization errors in Webex Calling logs

  2. ​​Security Protocols​​

    • 512-bit SHA-2 cryptographic hashing prevents MITM attacks during OTA updates
    • Validates against Cisco’s PKI infrastructure through embedded X.509 certificates
    • Addresses CVE-2024-3567 locale injection vulnerability patched in CUCM 15.0.1.90

  3. ​​Unified Management​​

    • Compatible with Cisco Prime Collaboration 12.8 for batch deployment
    • Reduces locale database memory usage by 18% compared to v15.0.0.1-89
    • Adds Webex Assistant UK English acoustic model optimizations
