​​Introduction to ps-locale-en_GB-15.0.1.2000-1.cop.sha512​​

This cryptographic hash-verified software package delivers full British English (en_GB) localization for Cisco Unified Communications Manager (CUCM) 15.0 environments. Designed to comply with UK Government Digital Service (GDS) accessibility standards, it implements ISO/IEC 8859-15 character encoding for administrative interfaces and call detail records (CDRs). The SHA512 checksum ensures file integrity during deployment, adhering to Cisco’s Secure Development Lifecycle (SDL) and FIPS 180-4 cryptographic guidelines.

Compatible exclusively with CUCM 15.0 SU2 and later, this build (version 15.0.1.2000-1) resolves date formatting inconsistencies (DD/MM/YYYY vs MM/DD/YYYY) in collaborative tools like Cisco Webex Control Hub and Jabber Messaging.

​​Key Features and Technical Enhancements​​

  1. ​​Regional Compliance​​

    • Implements UK Companies Act 2006 requirements for £ currency symbols in billing reports
    • Supports 24-hour time format with UTC+0 timezone synchronization

  2. ​​Linguistic Precision​​

    • Localized spellcheck dictionaries for British English variants (e.g., “colour” vs “color”)
    • Enhanced postcode validation in location-based emergency services (999/112 routing)

  3. ​​Security Protocols​​

    • SHA512 checksum validation prevents supply chain tampering during OVA deployments
    • Fixes CVE-2025-1188 (locale-based memory leak) present in 14.x English localization packs

​​Compatibility and System Requirements​​

​​Component​​ ​​Supported Versions​​
CUCM Base System 15.0(1)SU2 or later
Cisco Unity Connection 15.0(1)SU2a
Prime Collaboration 15.0(1) with March 2025 patch
Supported Hardware Platforms UCS C220 M8/C240 M8 servers

​​Release Date​​: Q2 2025 (Per Cisco’s quarterly software roadmap)
​​Critical Notes​​:

  • Requires 7GB additional storage for extended linguistic databases
  • Incompatible with third-party SIP devices using ISO-8859-1 encoding

​​Deployment Limitations​​

  1. ​​Functional Constraints​​

    • No automatic conversion between en_GB and en_US locale packs
    • British English TTS requires separate license (L-CUCM-TTS-UK)

  2. ​​Migration Considerations​​

    • Legacy en_US locale packs must coexist for audit log compatibility
    • Cluster-wide service restart required post-installation
