1. Introduction to ps-locale-sr_RS-15.0.1.2000-1.cop.sha512

This cryptographic checksum file validates the integrity of the Serbian (Serbia) localization package for Cisco Unified Communications Manager (CUCM) 15.0.1. Designed to comply with EU multilingual directives and Serbia’s Regulatory Agency for Electronic Communications (RATEL) standards, it provides full Cyrillic/Latin script support for administrative interfaces, audit logs, and technical documentation in modern Serbian.

Released in Q1 2025 as part of Cisco’s Balkan localization initiative, the package operates with CUCM 15.0.1 clusters on Cisco UCS C220/C240 M7 servers or VMware ESXi 8.0+/KVM 5.2+ virtual environments. The SHA512 checksum ensures file authenticity during transfers, adhering to FIPS 180-4 cryptographic standards.

2. Key Features and Technical Enhancements

​​Regional Compliance​​

  • Dual-script support (Cyrillic/ISO 8859-5 and Latin/ISO 8859-2 encoding)
  • Localized date formats (DD.MM.YYYY) with Serbian month abbreviations
  • DIN 1450-compliant typography for technical documentation

​​Security Validation​​

  • 512-bit SHA-2 hashing prevents MITM attacks during OTA updates
  • TLS 1.3 encryption enforced for all download operations

​​System Optimization​​

  • 30% faster Cyrillic text rendering compared to CUCM 14.x versions
  • Reduced memory footprint (82MB average vs. 120MB in 14.SU3)

​​Multi-Platform Support​​

  • Compatible with Webex Calling hybrid configurations
  • Validates UTF-8 encoding across Cisco Prime Collaboration 15.0 platforms

3. Compatibility Requirements
