Introduction to cm-locale-lt_LT-12.5.1.5000-1.cop.sgn Software

The ​​cm-locale-lt_LT-12.5.1.5000-1.cop.sgn​​ is a specialized localization component engineered for Cisco Unified Communications Manager (CUCM) deployments requiring Lithuanian (lt_LT) language support. Designed under Cisco’s Global Localization Initiative, this COP file enables full linguistic adaptation of administrative interfaces, call detail records, and system-generated notifications in compliance with Baltic region operational standards.

Validated for CUCM 12.5(1)SU2 and later releases, the module implements ISO 15924 script standards for Lithuanian diacritical characters (ą, č, ę, ė, į, š, ų, ū, ž). Its architecture maintains compatibility with Cisco’s Security Hardening Framework while supporting Extended Validation (EV) SSL certificates for secure locale data transmission.
