Introduction to cm-locale-pt_PT-12.5.1.4000-1.cop.sgn Software

This localization package provides native Portuguese (Portugal) language support for Cisco Unified Communications Manager (CUCM) 12.5.1 systems, designed to comply with ANACOM (Portuguese National Communications Authority) 2024 regulations for telecommunications infrastructure. Released in Q2 2025, it resolves diacritical rendering conflicts in administrative interfaces and call detail records (CDRs), specifically addressing orthographic standardization under the European Portuguese Language Orthographic Agreement. Compatible with CUCM clusters running 12.5(1)SU4+ on Red Hat Enterprise Linux 8.8 derivatives, it implements ISO/IEC 10646:2023 Unicode standards for Iberian character sets.
