​​Introduction to cm-locale-combined_network-12.5.1.3000-1.cop.sgn​​

This combined network locale package enables standardized telephony infrastructure configurations across multinational Cisco Unified Communications Manager (CUCM) 12.5 deployments. Designed to resolve regional tone/annunciator conflicts in global UC clusters, it unifies 23 country-specific network parameters including dial tone frequencies, call progress tones, and emergency service patterns. Released on February 28, 2025, this Cisco Options Package (COP) is mandatory for organizations operating CUCM in regions with overlapping country codes (e.g., Middle East/Africa cross-border deployments).

The software implements ITU-T E.164-compliant numbering plans while maintaining backward compatibility with legacy PBX systems. Compatible with CUCM 12.5(1) SU6 and later, it requires prior installation of Base Network Locale 12.5.1c. Regional variants cover EMEA, APAC, and Americas telecom regulations.

​​Key Features and Improvements​​

  • Implements dual-tone multi-frequency (DTMF) mapping for 60+ country code overlays
  • Resolves 3500Hz/440Hz dial tone conflicts in Middle East-Africa border regions
  • Adds ITU-T Q.23 compliant call waiting tones for GCC nations

​​2. Emergency Services Optimization​​

  • Synchronizes 112/911/999 emergency routing tables across clusters
  • Fixes SIP INFO message latency during multi-region E911 calls

​​3. Cryptographic Enhancements​​

  • Implements FIPS 140-3 validated TLS 1.3 cipher suites for international SIP trunks
  • Addresses CSCwh8302 vulnerability: DTMF injection via unsecured RTP streams

​​4. Diagnostic Tools​​

  • Introduces show network-locale compatibility CLI command
  • Generates locale conflict reports in Cisco Unified Reporting Tool
