Introduction to uc-locale-ar_SA-14.0.0.1-28.cop.sha512

The ​​uc-locale-ar_SA-14.0.0.1-28.cop.sha512​​ is a critical localization component for Cisco Unified Communications Manager (UCM) deployments requiring Arabic language support tailored to Saudi Arabian regional standards. This SHA-512 signed package enables full right-to-left (RTL) text rendering, Hijri calendar integration, and compliance with Saudi Communications, Space & Technology Commission (CST) regulations.

Certified for ​​Cisco Unified Communications Manager Release 14.0(0)​​, the software aligns with Unicode 15.0 Arabic script specifications and SASO TR 102-2024 technical requirements for enterprise telephony systems. The “.sha512” extension ensures FIPS 140-3 validated cryptographic verification for secure deployment integrity checks.

Key Technical Specifications & Enhancements

1. Regional Compliance

  • Implements ​​ar_SA​​ locale standards:
    • Arabic numeral formatting for call detail records (CDR)
    • Emergency service routing for Saudi-specific numbers (911/999/993)
    • SAR currency symbols in billing interfaces

2. Network Localization

  • Integrates Saudi-specific configurations:
    • Time zone synchronization (AST: UTC+3)
    • Mobile number prefix recognition (05x series)
    • National address database alignment for E.164 numbering

3. Security Architecture

  • Resolves CVE-2025-4187 (locale injection vulnerability)
  • SHA-512 hash validation prevents unauthorized package tampering
  • Hardware Root of Trust integration for UCS C-Series servers

4. Performance Optimization

  • 30% faster Arabic glyph rendering compared to 12.x locale packages
  • Reduced memory consumption (2.4GB → 1.7GB per cluster node)

Secure Acquisition Process

To obtain ​​uc-locale-ar_SA-14.0.0.1-28.cop.sha512​​:

  1. Visit Cisco Software Center
  2. Navigate to ​​Collaboration Solutions > Unified CM > 14.0(0)​​
  3. Select ​​Locale Packages​​ under “Supplemental Software”
  4. Complete dual authentication:
    • Valid Smart License (ENT-UC-5Y or equivalent)
    • CCO account with software download privileges

For government entities requiring air-gapped deployment, submit an SFTP request via [email protected] to receive FIPS 197-compliant encrypted media with embedded SHA-512 verification manifests.

This technical overview provides essential implementation guidelines for Arabic-language Cisco UC systems in Saudi Arabia. Always validate cryptographic signatures against Cisco PSIRT-2025-4190 before cluster-wide deployment.

​​Verification Requirements​​:

  1. Confirm SHA-512 hash matches a94a8fe5cc... (full value in PSIRT-2025-4190)
  2. Validate Cisco digital certificate via PKCS#11 cryptographic module
  3. Test RTL alignment in Cisco Unified Reporting dashboards

Note: Simultaneous installation across all publisher/subscriber nodes is mandatory to ensure linguistic consistency.
