The UC-to-UC Device report can provide you with metrics showing the performance levels of various endpoint devices on your network during unified communications-to-unified communications (UC-to-UC) calls, to help you identify devices that are performing poorly. The metrics used focus on conversational quality and acoustic measures. By default, the report shows all capture devices so that you can compare performance across devices.

For each device type, the report displays the following:

Additionally, for Office Communicator endpoints only, the Speech/Echo, Speech Level, Background Noise, and Background Noise Sent are shown.

You can sort the results by each column. Overall quality score averages for all devices are shown at the top of each data column, so that you can compare each individual device’s scores with the overall average.

In this list, you can click the name of a device and see a list of individual calls that involved the device, and the quality scores for each call.


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

  • Location Scope.You can include all locations in the report, or filter it down to one or two locations (that is, selected in Location 1and Location 2), or even to specific callers within those locations (that is, selected in Caller/Callee). If you filter to specific locations, the data about all calls to or from either of those locations are shown.

  • Exclude External Calls.Select this to exclude calls where either the sender or receiver are located outside of the enterprise network. Note that this is Trueby default; select Falseto include external calls in the report.

  • Media Connectivity.Use this to choose only calls that are directly connected (that is, by users within the enterprise), or calls that use the A/V Edge service or the HTTP Proxy to be connected (that is, calls that involve external users).

  • Client Type.Use this filter to view the quality of calls on specific client types, such as Office Communicator, Office Communicator Phone Edition, or Office Communications Server 2007 R2 Attendant.

  • Capture Device prefix.In this filter, you can type a partial string, and the report will show only devices with descriptions that begin with that string. Examples of useful strings to type here would be headsetor microphone.

    If you leave this filter blank the report will query for all devices, and the report might take a long time to generate on large networks.


  • On your network you have newer and older versions of Office Communicator Phone Edition, as well as different devices used with Office Communicator. To assess the performance of various devices, you can set Capture Device prefixto telephone, and get a list of metrics for phones, sorted by version number.
