Introduction to ciscocm.V15SU1_CSCwk34745-devicetlinfo_C0222-1.zip

This SHA512-verified enhancement package delivers advanced device telemetry collection capabilities for Cisco Unified Communications Manager (CUCM) 15.0SU1 deployments. Designed to strengthen network observability in enterprise collaboration environments, it introduces real-time monitoring of 78 device health metrics across Cisco IP Phone 9800 Series and Video Phone 8875 endpoints.

The “CSCwk34745” bug ID indicates resolution of telemetry data sampling inconsistencies reported in CUCM 14.x environments. This ZIP archive contains encrypted configuration templates that implement RFC 8345-compliant YANG data models for telemetry collection, optimized for Cisco’s 64-bit collaboration platform architecture.
