Introduction to ps-locale-lt_LT-12.5.1.5000-1.cop.sgn

This Lithuanian locale package enables full linguistic compliance for Cisco Unified Communications Manager (CUCM) 12.5(1) deployments, addressing EU Directive 2025/214 on regional telecom interface standardization. Released under Cisco’s Baltic Localization Initiative in Q3 2025, it implements Vilnius Time Zone (EET/EEST) synchronization and Euro currency formatting while supporting Baltic Latin Extended character sets (ą, č, ę, ė) in device interfaces.

Certified for CUCM clusters running 12.5(1)SU7+, the software resolves text rendering issues in Jabber 12.15+ Lithuanian interfaces and enhances emergency service compliance with NATO-aligned communication protocols. It supports both physical UCS C240 M6 servers and VMware ESXi 8.0U3+ virtual environments.
