How UC Monitor Works

UC Monitor actively and passively monitors call quality in unified communications environments. The product 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 end-of-call quality metrics to their call server. The collector inspects these flows for performance metrics.
• Each Microsoft instance reports end-of-call quality metrics to the Lync collector.
• Using RTCP, Avaya endpoints send in-progress call quality metrics 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. The product measures and analyzes the performance of VoIP-related call setup protocols. Supported collection devices send relevant call quality data to the database for analysis and reporting.

• The collector transmits only the data necessary to calculate and report about call setup and call quality 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. The product monitors data flows between the origination device and the destination call server or media device to evaluate the performance of call setup.
