Introduction to cm-locale-combined_network-12.5.1.4000-1.cop.sgn

This digitally signed Cisco Operations Package (COP) provides consolidated network locale configurations for Cisco Unified Communications Manager (CUCM) 12.5.1 environments, delivering country-specific telephony tone profiles and gateway compatibility parameters across 28 EMEA/APAC regions. Designed for multinational enterprises, the combined network locale package resolves interoperability issues between Cisco collaboration devices and national PSTN networks by standardizing call progress tones, DTMF mappings, and emergency service patterns.

Certified under Cisco’s Q2 2025 global compliance initiative, this release incorporates updated ITU-T E.164 country code validations and GDPR-compliant call metadata formatting. System administrators should note the mandatory cluster-wide deployment requirement for consistent tone generation across distributed nodes.

Key Features and Improvements

  1. ​​Multi-Regional Tone Standardization​​
    Implements 17 new national telephony profiles including Ofcom UK 2025 tone specifications and Germany’s BNetzA TAFv7.3 requirements, resolving PRI gateway compatibility issues reported in CVE-2024-44771.

  2. ​​Security Enhancements​​

  • Encrypted TLS 1.3 transport for locale synchronization between publisher/subscriber nodes
  • FIPS 140-3 validated signature verification prevents unauthorized tone profile modifications

  1. ​​Diagnostic Tool Integration​​
    Generates automated compliance reports via CUCM CLI command utils network locale verify, comparing active configurations against regional telecom authority standards.

  2. ​​Bandwidth Optimization​​
    Reduces SIP packet size by 22% through compressed G.722.1C codec mappings for international gateway deployments.

Compatibility and Requirements

Component Supported Versions Technical Prerequisites
CUCM 12.5(1)SU4+ 8GB free disk space
OS Platform Red Hat Enterprise Linux 7.9 glibc 2.17-324+
Gateways Cisco ISR 4451-X IOS XE 17.8.1a+
Security TLS 1.3 FIPS mode enabled

Deployment requires temporary disablement of Cisco Unified Border Element services and removes legacy network locale packages (version <12.5.1.3000) during installation. Incompatible with third-party NTP implementations using SHA-1 authentication.

Limitations and Restrictions

  1. Custom tone configurations in User Device Profiles will be overwritten post-installation
  2. Historical CDR records retain original DTMF timing metadata formats
  3. Simultaneous installation with user locale packs requires sequential reboot cycles
