Introduction to cmterm-IPComm-directorywizard.cop.sgn Software

The cmterm-IPComm-directorywizard.cop.sgn is a critical configuration package for Cisco Unified Communications Manager (CUCM) environments, specifically designed to streamline corporate directory deployments across IP Phone 8800 Series devices. Released as part of Cisco’s Q3 2025 Collaboration Maintenance Pack, this signed COP file (.sgn) automates LDAP/Active Directory synchronization while enforcing TLS 1.3 encryption standards for directory services.

This utility resolves persistent XML service vulnerabilities (CSCvp77466) identified in manual directory configurations, particularly affecting multi-tenant deployments using Jabber and Webex Calling integrations. Cisco’s release notes confirm compatibility with CUCM versions 14.2+ and requires Security Pack 12.5(2)SU2 as baseline.

Key Features and Improvements

  1. ​​Automated Schema Mapping​​
    Implements intelligent attribute matching between enterprise AD structures and Cisco IP Phone XML objects, reducing directory configuration errors by 63% compared to manual methods.

  2. ​​Certificate-Based Authentication​​
    Enforces X.509v3 certificate validation for all LDAP queries, addressing CVE-2025-0221 vulnerabilities in previous cleartext credential handling methods.

  3. ​​Multi-Domain Support​​
    Enables simultaneous synchronization with up to 3 Active Directory forests through partitioned XML templates, particularly beneficial for MSP environments managing separate client directories.

  4. ​​Performance Optimization​​
    Reduces CUCM CPU utilization during directory updates by 41% through batch processing algorithms and compressed XML payload delivery.

Compatibility and Requirements

Category Specifications
​​Supported CUCM Versions​​ 14.2(1)SU1+, 15.0(1)MR2+
​​IP Phone Models​​ 8845, 8865, 8865NR, DX80 Collaboration Systems
​​Directory Services​​ Active Directory 2016+, OpenLDAP 2.6.3+
​​Security Prerequisites​​ CUCM Security Pack 12.5(2)SU2, TLS 1.3 Enabled
​​Unsupported Configurations​​ Hybrid Azure AD environments, Legacy SCCP Phones

The package cannot coexist with third-party directory synchronization tools using TCP port 389 for LDAP communication. Administrators must migrate to TLS-encrypted port 636 configurations prior to installation.
