​​Introduction to ps-locale-th_TH-12.5.1.4000-1.cop.sgn​​

The ​​ps-locale-th_TH-12.5.1.4000-1.cop.sgn​​ is a specialized localization package designed for Cisco Unified Communications Manager (CUCM) environments requiring compliance with Thai language standards and Thailand’s telecommunications regulations. Released in Q3 2025, this software ensures accurate rendering of Thai script, date formats (DD/MM/YYYY BE), and currency symbols (฿) across CUCM administrative interfaces and endpoint devices.

This SHA-512 signed package supports ​​CUCM 12.5(1) SU4​​ and later versions, aligning with Thailand’s National Broadcasting and Telecommunications Commission (NBTC) guidelines. It enables seamless integration with Cisco IP phones, Webex Calling, and Jabber clients in hybrid deployments, ensuring compliance with Thailand’s Personal Data Protection Act (PDPA).

​​Key Features and Improvements​​

  1. ​​Regional Compliance Enhancements​​

    • Implements ​​th_TH.UTF-8​​ locale standards for Buddhist Era (BE) calendar integration in Cisco Unity Connection voicemail timestamps.
    • Resolves Thai script rendering issues in Cisco IP Phone 8865 and DX80 status screens.

  2. ​​Security and Protocol Upgrades​​

    • Integrates TLS 1.3 cipher suites for secure localization data transmission between CUCM clusters and endpoints.
    • Addresses CVE-2025-13201 (CVSS 7.2), a locale-specific 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 IVR systems.

  4. ​​Administrative Efficiency​​

    • Enables bulk deployment via Cisco Prime Collaboration 12.7 templates, reducing manual configuration time by 40% (Cisco TAC metrics).
    • Adds automated locale validation logs in Cisco Unified Real-Time Monitoring Tool (RTMT) for compliance audits.
