Introduction to cmterm-devicepack14.0.1.13029-1.cop.sha512

This device pack provides firmware updates and feature enhancements for Cisco Unified Communications Manager (CUCM) 14.0.1-managed endpoints. Released under Cisco’s Q3 2025 maintenance cycle, it addresses critical interoperability issues between CUCM 14.0.1 and newer IP phone models while maintaining backward compatibility with legacy devices.

The package supports SHA-512 cryptographic validation for secure deployment and includes firmware binaries for 18 Cisco IP phone models. Compatible with CUCM clusters running 14.0.1.12900-161 or later, it resolves device registration failures caused by TLS 1.3 cipher suite mismatches in previous versions.
