This topic goes through some troubleshooting scenarios using multiple Monitoring Server reports, to illustrate how they can be used together to correct media quality issues.
You are receiving reports of audio distortion form a building that has recently switched to unified communications (UC) telephony. You start by looking at the summary\trends reports, filtering to that location, but find nothing significant except that Conversational mean opinion score (MOS) is a little lower than in other locations.
You move on to the device reports and filter to that location, and compare the quality scores for each device to the averages shown at the top of each column. You find that most devices are functioning properly, but that one type of headset has very high numbers for Background Noise and Noise Sent. Further investigation reveals that the headset in question is used only in that building, and its design is the cause of the problems.
Your organization employs many different devices with no strict guidelines enforced for device choice. You are receiving complaints about audio quality from users with various devices. To determine what devices are causing these problems, you use the Capture Device filter in the UC-to-UC Summary\Trends and the PSTN Summary\Trends reports, looking at the data for individual device types. You discover that the Sending MOS, Listening MOS, and Conversational MOS scores show some IP phones with very low quality ratings in the PSTN Summary\Trends report.
You then run the PSTN Device Report, and confirm that the quality scores for that IP phone are lower than other devices. You then click on that IP phone name in this report, and see a list of individual calls using the phone, and track down the problems to specific phones of that type.
