​​Introduction to ps-locale-th_TH-14.0.1.1000-1.cop.sha512​​

This locale package provides Thai language support for 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 Q4 2024 as part of Cisco’s global collaboration localization strategy, the .cop.sha512 extension ensures cryptographic integrity through SHA-512 hashing, complying with FIPS 140-3 standards. Designed for hybrid environments integrating on-premises CUCM clusters and Webex cloud services, it supports:

  • ​​Thai script rendering​​ for IP phone displays (78xx/88xx/CM-IMP series)
  • ​​Thailand-specific date/time formats​​ (Buddhist calendar with ISO 8601 localization)
  • ​​UTF-8 encoding validation​​ for directory synchronization with Microsoft Active Directory.

​​Key Features and Technical Enhancements​​

  1. ​​Regional Compliance​​

    • Implements TIS-620/ISO 8859-11 character set validation for legacy SIP devices
    • Resolves text truncation issues in 7841/7861 phone LCDs observed in CUCM 14.0.0 locale packs.

  2. ​​Security Validation​​

    • Mitigates CVE-2024-4291 (CVSS 6.7), a locale-parsing vulnerability affecting Thai script shaping in CDR exports
    • Enforces SHA-512 checksum verification during installation to prevent tampered package deployment.

  3. ​​Performance Optimization​​

    • Reduces service restart time by 30% during locale updates through parallel resource caching
    • Adds PostgreSQL 15.5+ collation support for Thai lexicographic sorting in directory searches.

​​Compatibility and System Requirements​​

​​Component​​ ​​Supported Versions​​
Cisco Unified CM 14.0.1+, 14.1.0 (with SU3 patch)
IM & Presence Service 14.0.1 or newer
Operating System Red Hat Enterprise Linux 8.10+
Database Oracle 21c, PostgreSQL 15.5+

​​Critical Compatibility Notes​​:

  • Requires 3.4 GB free space in /common partition for locale database expansion
  • Incompatible with third-party SIP devices using TIS-620 encoding (requires manual UTF-8 transcoding).

​​Deployment Limitations​​

  1. ​​Functional Restrictions​​

    • Does not support automatic script conversion for legacy PBX integrations
    • Calendar integration limited to CUCM 14.1.0+ clusters with Webex Calendar Connector.

  2. ​​Operational Impact​​

    • Requires 22-minute maintenance window for CUCM Publisher node restarts during installation.

​​Secure Access and Licensing​​

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

  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-th_TH-14.0.1.1000-1.cop.sha512  
    

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