Andrew Sniderman and Jens Trier Rasmussen are program managers for Lync.
The Lync team wants your users to be delighted about the quality of every Lync call they make. We built the new Call Quality Methodology (CQM) scorecard to help you reach this goal. The CQM scorecard was released in the June update of the Lync Network Guide. The Call Quality Methodology is described in Appendix C of the guide. The scorecard is an Excel spreadsheet that loads all the CQM query results and creates a number of views that will help you analyze and fix call quality problems in your Lync implementation.
A peak into the scorecard
Included in the Network Guide download is a powershell script (CQM.ps1) that automates the execution and collection of the SQL queries discussed in the Network Guide. When you point the scorecard at your data, it will generate a bunch of views so you can get a handle on the distribution of audio streams in your environment, which ones are showing a high percentage of poor streams and how they are trending over time. The scorecard view then presents all this in a summary table that correlates with the ten elements of CQM just as you see in the CQM poster. The areas are grouped by Red (Server Plant), Blue (Last Mile) and Green (Endpoints). A final area is classified as Unmanaged at the bottom which shows all external streams (media streams originating on the internet and coming into Lync via Edge servers).
