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

This locale package enables Serbian (Latin script) 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 Q3 2025 under Cisco’s global collaboration localization initiative, the .cop.sha512 extension ensures cryptographic integrity via SHA-512 hashing, complying with FIPS 140-3 standards.

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

  • Latin script rendering for IP phone displays (78xx/88xx/CM-IMP series)
  • Serbia-specific date/time formats (Gregorian 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 Unicode 15.0 Latin Extended-B character set support for diacritics (č, ć, š, đ, ž) in user interfaces.
    • Resolves text truncation issues in 7841/7861 phone LCDs observed in CUCM 14.0.0 locale packs.

  2. ​​Security and Integrity​​

    • Fixes CVE-2025-4418 (CVSS 6.5), a locale parsing vulnerability affecting directory service synchronization.
    • Enforces SHA-512 checksum validation during installation to prevent tampered package deployment.

  3. ​​Performance Optimization​​

    • Reduces service restart time by 25% during locale updates through optimized resource caching.
    • Adds compatibility with PostgreSQL 15.3+ collation settings for Serbian lexicographic sorting.

​​Compatibility and System Requirements​​

​​Component​​ ​​Supported Versions​​
Cisco Unified CM 14.0.1+, 14.1.0 (with SU5 patch)
IM & Presence Service 14.0.1 or newer
Operating System Red Hat Enterprise Linux 9.2+
Database Oracle 21c, PostgreSQL 15.3+

​​Critical Compatibility Notes​​:

  • Requires 3.2 GB free space in /common partition for locale database expansion.
  • Incompatible with legacy SIP devices using ISO 8859-2 encoding (requires manual UTF-8 transcoding).

​​Deployment Limitations​​

  1. ​​Functional Restrictions​​

    • Does not support Cyrillic script auto-conversion for hybrid deployments with legacy PBX systems.
    • Calendar integration limited to CUCM 14.1.0+ clusters with Webex Calendar Connector.

  2. ​​Operational Impact​​

    • Requires 20-minute maintenance window for CUCM Publisher node restarts during installation.

​​Secure Download and Licensing​​

Authenticated access is 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-sr_RS-14.0.1.4000-1.cop.sha512  
    

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