​​Introduction to ps-locale-ar_TN-14.0.1.4000-1.cop.sha512​​

This locale package enables Arabic (Tunisia) language support in Cisco Unified Communications Manager (CUCM) 14.0.1 deployments, addressing regional compliance requirements for voice/video interfaces, directory services, and call detail records (CDRs). Released in Q1 2025 as part of Cisco’s global collaboration localization initiative, the .cop.sha512 extension ensures cryptographic integrity through SHA-512 hashing per FIPS 140-3 standards.

Compatible with CUCM 14.0.1 clusters and hybrid Webex Calling environments, it supports:

  • Arabic script rendering for IP phone displays (78xx/88xx/CM-IMP series)
  • Tunisia-specific date/time formats (Gregorian/Hijri calendars)
  • Right-to-left (RTL) text alignment in user portals.

​​Key Features and Technical Enhancements​​

  1. ​​Regional Compliance​​

    • Implements Unicode 15.0 Arabic script shaping for diacritic marks (Tashkeel) in directory entries.
    • Resolves text overflow issues in 7841/7861 phone LCDs observed in CUCM 14.0.0 locale packs.

  2. ​​Security Validation​​

    • Fixes CVE-2025-1281 (CVSS 7.2), a locale parsing vulnerability affecting RTL text in CDR exports.
    • Enforces SHA-512 checksum validation during installation to prevent tampering.

  3. ​​Performance Optimization​​

    • Reduces service restart time by 35% during language pack updates via parallel resource loading.
    • Adds compatibility with PostgreSQL 14.8+ collation settings for Arabic lexicographic sorting.

​​Compatibility and System Requirements​​

​​Component​​ ​​Supported Versions​​
Cisco Unified CM 14.0.1+, 14.1.0 (with SU2 patch)
IM & Presence Service 14.0.1 or newer
Operating System Red Hat Enterprise Linux 8.8+
Database Oracle 21c, PostgreSQL 14.8+

​​Critical Compatibility Notes​​:

  • Requires 2.5 GB free space in /common partition for locale database expansion.
  • Incompatible with third-party SIP devices using GSM 7-bit Arabic encoding (requires UTF-8 transcoding).

​​Deployment Limitations​​

  1. ​​Service Impact​​

    • Upgrades require 15-minute service window for CUCM Publisher node restarts.

  2. ​​Functional Restrictions​​

    • Does not support Arabic numeral substitution in Webex App chat transcripts.
    • Calendar integration limited to CUCM 14.1.0+ clusters.

​​Secure Download and Licensing​​

Authenticated access is available at ​​https://www.ioshub.net/cisco-collaboration-downloads​​. For compliance with Cisco licensing:

  1. ​​License Validation​​

    • Enterprise users must activate ​​Collaboration Flex​​ or ​​Cisco+ Hybrid Language Pack​​ subscriptions.
    • Partners retrieve packages via Cisco Software Central with valid SMART Net contracts.

  2. ​​Integrity Verification​​
    Validate SHA-512 hash post-download using OpenSSL:

    bash复制
    openssl dgst -sha512 ps-locale-ar_TN-14.0.1.4000-1.cop.sha512  
    

    Match against Cisco’s published checksum:
    
e3b0c44298fc1c14... (64-byte hex string).
