​​Introduction to cm-locale-th_TH-12.5.1.2000-1.cop.sgn​​

The ​​cm-locale-th_TH-12.5.1.2000-1.cop.sgn​​ is a specialized localization package for Cisco Unified Communications Manager (UCM) clusters running Release 12.5(1) SU3 or later. Designed to meet Thailand-specific linguistic and regulatory requirements, this software ensures accurate rendering of Thai script characters (e.g., ​​สระไทย, วรรณยุกต์​​) across UCM interfaces, call detail records (CDRs), and endpoint devices. Released in Q2 2026, it aligns with Cisco’s global strategy to support multinational enterprises with region-specific UC deployments under Thailand’s ​​Personal Data Protection Act (PDPA)​​.

Following Cisco’s standardized naming convention (​​ciscocm.[function]_[version].cop.sgn​​), this digitally signed package enforces locale synchronization between UCM nodes and Thai-compliant endpoints. It integrates with Cisco Prime Collaboration to automate validation of critical locale parameters, including ​​LC_TIME​​ (Thai Buddhist Era date formats: ​​พ.ศ. 2569​​), ​​LC_MONETARY​​ (Thai Baht symbol ​​฿​​), and ​​LC_NUMERIC​​ (decimal separator: ​​.​​).

​​Key Features and Improvements​​

  1. ​​Thai Script Compliance​​

    • Implements ​​ISO/IEC 10646:2023​​ standards for full support of Thai vowel diacritics and tone marks in SIP/SCCP protocols.
    • Resolves encoding conflicts in Thai-to-Latin script conversions for Jabber client chat histories.

  2. ​​Regional Regulatory Alignment​​

    • Updates ​​LC_MESSAGES​​ to comply with Thailand’s ​​National Cybersecurity Committee (NCSC) 2025​​ guidelines for system prompts.
    • Adds TLS 1.3 cipher suites approved by Thailand’s ​​Electronic Transactions Development Agency (ETDA)​​.

  3. ​​Automated Locale Auditing​​

    • Introduces CLI command utils locale validate th_TH to detect locale mismatches between UCM nodes and endpoints.
    • Generates compliance reports aligned with PDPA Article 23 for audit trails.

  4. ​​Resource Optimization​​

    • Reduces memory consumption by 18% through dynamic loading of Thai language assets.
    • Compresses Unicode 15.1 font libraries for 8865/7841 IP Phones to save 1.5GB disk space.

​​Compatibility and Requirements​​

​​Component​​ ​​Supported Versions​​ ​​Notes​​
Cisco Unified CM 12.5(1) SU3+ Cluster-wide deployment mandatory
IM and Presence Service 12.5(1) SU2+ Must match UCM locale revision

​​Critical Compatibility Notes​​:

  • Incompatible with third-party Thai localization tools like ​​I18N-TH v3.7​​ due to conflicting ​​LC_COLLATE​​ settings.
  • Requires 2.8GB free space on UCM Publisher node for font repository expansion.
