Updated: April 24, 2026

Want to summarize with AI?

This task allows you to monitor the real-time statuses of lines, calls, interfaces, and related items that a device processes after enabling UC voice services for supported routers.

Monitoring UC operations provides crucial insights into the performance and status of your Unified Communications deployment, helping you verify functionality and troubleshoot issues.
