1. Introduction to cm-locale-combined_network-5.0.4.1-2.cop.sgn

This cryptographic network locale package consolidates region-specific telephony configurations for Cisco Unified Communications Manager (CUCM) 12.5 deployments. Designed to standardize international telephony parameters, it integrates 38 country-specific network profiles including DTMF tones, call progress tones, and emergency service routing rules.

The “.sgn” extension denotes Cisco’s Secure Generic Notation format, ensuring FIPS 140-3 compliance for enterprise telephony systems. Released on March 15, 2025, this version supports CUCM clusters running 12.5(1)SU2 or newer, with backward compatibility for hybrid 11.x/12.x environments during phased upgrades.
