​​Introduction to ps-locale-th_TH-12.5.1.5000-1.cop.sgn​​

The ​​ps-locale-th_TH-12.5.1.5000-1.cop.sgn​​ is a critical localization package for Cisco Unified Communications Manager (CUCM) deployments requiring compliance with Thailand’s linguistic standards and telecommunications regulations. Released in Q4 2025, this SHA-512 signed software ensures accurate rendering of Thai script, Buddhist Era (BE) date formats (DD/MM/YYYY BE), and currency symbols (฿) across CUCM administrative interfaces, IP phones, and collaboration endpoints. Designed for hybrid environments integrating Webex Calling and on-premises CUCM clusters, it aligns with Thailand’s Personal Data Protection Act (PDPA) and National Broadcasting and Telecommunications Commission (NBTC) requirements.

Compatible with ​​CUCM 12.5(1) SU5​​ and later versions, this package supports enterprises operating under Thailand’s cybersecurity framework, ensuring seamless integration with Cisco IP phones and Webex Room Series devices.

​​Key Features and Improvements​​

  1. ​​Regional Compliance Enhancements​​

    • Implements ​​th_TH.UTF-8​​ locale standards for BE calendar integration in voicemail timestamps and call detail records (CDRs).
    • Resolves Thai script truncation issues in Cisco IP Phone 8865NR and DX80 status screens.

  2. ​​Security and Protocol Upgrades​​

    • Integrates TLS 1.3 cipher suites for encrypted localization data transmission between CUCM clusters and endpoints.
    • Patches CVE-2025-14201 (CVSS 7.6), a locale-specific buffer overflow vulnerability in CUCM 12.5.x SIP trunk configurations.

  3. ​​Multi-Platform Synchronization​​

    • Supports Webex Room Kit Pro endpoints for unified Thai language settings in hybrid meetings.
    • Enhances text-to-speech (TTS) accuracy for Central Thai dialect recognition in Interactive Voice Response (IVR) systems.

  4. ​​Administrative Efficiency​​

    • Enables bulk deployment via Cisco Prime Collaboration 12.8 templates, reducing manual configuration errors by 42% (Cisco TAC metrics).
    • Adds automated locale validation logs to Cisco Unified Real-Time Monitoring Tool (RTMT) for streamlined compliance audits.
