When enabled in the VeloCloud Orchestrator, VeloCloud Voice Quality Monitoring (VQM) diagnoses, monitors, and troubleshoots network issues that impact voice communications.

Note: The Voice Quality Monitoring (VQM) feature will be deprecated in future releases.
VQM supports 80+ Voice Codecs and provides listening and conversational call quality metrics in both R-Factor and MOS (mean opinion score) formats as well as detailed diagnostic information.

These report metrics provide a high-level health overview of the network and specific details of each call session, which get sent to a RFC6035 compliant VQM Collector (e.g. Oracle Palladion, Telchemy SQMediator, etc.). If there are multiple reports sent from a single call session, the VQM collector will correlate these reports into a single coherent quality record.


Enabling Voice Quality Monitoring

To enable Voice Quality Monitoring (VQM):

  1. Go to Configure > Edges > Device tab.
  2. Scroll down to the Voice Quality Monitoring Settings area. (See image below).


  3. Check the Enabled checkbox to enable VQM.
  4. From the Protocol drop-down menu, select the Protocol.
  5. In the Collectors text box, type in the IP Address and Port number of the location where you would like to receive the Voice Quality metric reports. To add multiple IP Addresses and Ports, click the " +" symbol. To delete a Collector, click the " -" symbol.
  6. If applicable, check the Enable Edge Override checkbox. Hover over the symbol of the "triangle exclamation point" to view the pop up message (as displayed in the image above).
