How UC Monitor Works

UC Monitor performs passive and active monitoring of call quality in unified communications environments. UC Monitor does not actually listen to calls. Most call performance measurements are derived from data flows to and from the call servers. For example:

• Cisco endpoints An endpoint is any device where a media stream begins or ends, such as telephone, softphone, telepresence, voice gateway, media device, and video camera. report quality data to their call server at the completion of every call. The UC Monitor collector inspects these flows for performance metrics.
• Each Microsoft instance reports end-of-call quality metrics to the Lync collector.
• Avaya endpoints use RTCP to send in-progress call quality reports directly to the collector. The collector uses SNMP to poll the Avaya Communication Manager for information.

Thresholds allow UC Monitor to detect performance exceptions and send alerts. UC Monitor measures and analyzes the performance of VoIP-related call setup protocols. At regular intervals, supported collection devices send relevant call quality data back to the database at the management console for analysis and reporting.

• The collector transmits only the data necessary to calculate and report about call setup and call quality for calls from Cisco or Avaya hardware.
• The Lync collector receives end-of-call quality reports from audio and video endpoints, posts them to the management console, and saves them as call detail records.

UC Monitor also gathers call quality and call setup data from media devices that support VoIP. UC Monitor monitors data flows between the origination device and the destination call server or media device to evaluate call setup performance.
