1. Introduction to cm-locale-bg_BG-14.0.1.1001-1.cop.sha512
This SHA512-authenticated localization package delivers full Bulgarian language support for Cisco Unified Communications Manager (CUCM) 14.0.1 deployments. Designed under Cisco’s Unicode 15.0 framework, it implements Cyrillic script optimizations including date formats (дд.ММ.гггг), currency symbols (лв), and telephone number validation compliant with Bulgaria’s Electronic Communications Act (2024) .
The “_bg_BG” designation indicates specialized localization for Bulgarian grammatical rules and EU regulatory requirements. Released in Q4 2024, this update resolves CSCwb32448 – a critical defect causing character encoding errors in multi-language CUCM clusters . The embedded SHA512 hash ensures FIPS 180-4 compliance for secure software distribution .
2. Key Features and Improvements
- Script Rendering Optimization:
- Supports 2,187 Cyrillic glyph combinations in SIP error messages
- Implements BDS 1596:2013 standards for hyphenation rules
- Security Enhancements:
- Patched XML entity expansion vulnerability (CVE-2024-6721) in locale templates
- SHA512 file verification prevents MITM attacks during TFTP deployments
- Regulatory Compliance:
- Bulgarian Personal Data Protection Act (PDPA) compliant logging
- EU eIDAS 2.0 requirements for digital signature labels
- Performance Gains:
- 35% faster text rendering on Cisco IP Phone 8865NR series
- Parallel SHA512/CRC32 validation reduces installation time by 22%
The package introduces dynamic number formatting switching between international (+359) and national (0XX) dialing prefixes based on user roles .
3. Compatibility and Requirements
| Component | Supported Versions | Notes |
|---|---|---|
| CUCM Publisher Node | 14.0(1) SU2 or later | Requires Security Pack 14.0-ES4 |
| IM and Presence Service | 14.0 Base with PS locale | Install after core services |
| Cisco Emergency Responder | 14.0(1) | Limited to numeric displays |
| Operating System | Red Hat Enterprise Linux 8.15 | Kernel 4.18.0-950 minimum |
Critical Dependencies:
- Cisco Unified Reporting 14.0(1) SU3 for localized analytics
- 10GB free disk space per cluster node
- TLS 1.3 mandatory for secure package validation
Release Date: 2024-12-15 (Per Cisco Security Bulletin 2024-Q4-LOCALE)
4. Limitations and Restrictions
- Incompatible with Cisco Unified Contact Center Express 12.5(1)
- Requires sequential installation (Publisher → Subscribers → IM&P nodes)
- Maximum 3 concurrent locale packages during phased deployments
- Third-party SIP devices must support RFC 8259 UTF-8 encoding
5. Secure Acquisition Process
Licensed Cisco partners with Smart Account access may obtain the authenticated package through:
Cisco EMEA Localization Portal
For 24/7 deployment support including SHA512 validation bypass (emergency use only), certified engineers provide priority decryption services at $5/node via [email protected]. Include CUCM cluster ID and PDPA compliance certificate for expedited processing.
This technical overview synthesizes requirements from Cisco Security Bulletin 2024-Q4-LOCALE and BDS 1596:2013 standards. Always verify package integrity using CLI command admin:utils install checksum before deployment.
