Location Based Performance Report

Topic Last Modified: 2009-07-21

The Location Based Performance report provides a list of network locations, and for each location shows the number of calls in each pre-determined range (or "bucket") of quality. The goal of this report is to provide insight into the media quality of the bulk of your calls for various locations, so that you can identify poorly performing locations, and see the different grades of media quality in your different locations.

When you display the report, different tables of metrics are displayed; one table for each metric you choose to report on. You can choose from the following metrics for this report:

  • Conversational mean opinion score (MOS)
  • Network MOS
  • Network MOS Degradation
  • Sending MOS
  • Listening MOS
  • Packet Loss
  • Jitter
  • Latency

You can sort the results by each column. You can click location to see the list of calls from that location, and the quality scores for each individual call. In this listing of individual calls, the overall average scores for that location"s calls are shown at the top of each column.

Filters

You can filter the data in this report based on the following:

  • Metrics. Select the check boxes for one or more metrics in this list. For each metric you select, a separate table of data will be shown in the report.

  • Location. Select one of the settings for the locations that have the most call activity (Top 5, Top 25, Top 50, Top 100), or select a specific location.

    Note

    You can use the location import feature of Monitoring Server to map multiple subnets to a physical location, which you can then select here in the Location filter. By doing this, you can group together a certain set of subnets and then see a report about their activity. For details on the location import feature, see Configuring Network Locations to Monitor.

  • Call Type. Use this filter to select the type of calls: UC-to-UC, UC-to-PSTN (in both directions), conference calls, or all types of calls.

Scenarios

  • You are receiving many reports of bad call quality from users in Location A. Start by using this report, choosing Location A in the location filter. You discover that the metrics reflecting network quality are the low values. You might then go on to check network usage during the times of bad call quality, and find that the poor-quality calls happen during peak usage hours, and then look to increase network capacity at that location.
  • Using this report and the Call Type filter, you find that at a certain location, unified communications-to-public switched telephone network (UC-to-PSTN) calls consistently have lower quality numbers than UC-to-UC calls. This may reveal that the Mediation Server for this location is overloaded or having network problems.
  • Conference calls for a particular location consistently are scored as low quality. Your investigation may lead to find that the A/V Conferencing Server for this location is accessed over a congested wide area network (WAN) link, which you need to increase bandwidth for.
