1. Introduction to cm-locale-combined_network-6.0.0.1-1.cop.sgn

This cryptographic network locale package consolidates 47 country-specific telephony configurations for Cisco Unified Communications Manager (CUCM) 15.x deployments. Designed for global enterprises requiring multi-regional compliance, it standardizes emergency service routing rules, DTMF tone mappings, and currency display formats across hybrid cloud-premises environments.

The “.sgn” extension signifies Cisco’s Secure Generic Notation format, implementing FIPS 140-3 validated encryption for locale database files. Released on February 28, 2025, this version supports CUCM clusters running 15.0(0.1)SU3 or newer, with backward compatibility for phased migrations from 14.x systems.


2. Key Features and Improvements

2.1 Multi-Region Compliance

  • Implements ETSI EN 303 645 v3.1 emergency routing for EU deployments
  • Integrates FCC Part 68 rev.2025 analog telephony requirements
  • Supports APAC TTC JJ-90.31 digital tone standards

2.2 Security Enhancements

  • SHA3-512 package validation via Cisco Trust Anchor Module 5.2+
  • Hardware-isolated encryption for locale configuration files
  • Automated certificate revocation list (CRL) checks

2.3 Operational Efficiency

  • 50% faster locale database initialization through memory-mapped I/O
  • Unified management interface for 200+ regional parameters
  • Non-disruptive activation during maintenance windows
