Find Lync Phone Edition Phones being used on Skype for Business Online



Since the news that Lync Phone Edition will no longer work on Skype for Business Online from October 31st 2018, I’ve been asked by a few customers, “how can I check if I have any Lync Phone Edition Phones on my Skype for Business Online”.

You can do this in Call Quality Diagnostics, which is included in Skype for Business Online for every customer at

In CQD you can create custom reports:

Go to Detailed Reports



Create a new report


Select Dimensions of First User Agent, First Network and Second Network.

First User Agent is the user’s device


From this we can then filter by “CPE” which is “Communications Phone Edition” which was the name before “Lync Phone Edition”.


If your networks are mapped in CQD this will show you where those phones are by subnet.

Unfortunately CQD does not hold user identifiable information, so doesn’t show who the users are. Third party reporting products like Modality Diagnostics can report who the users are (plug plug Smile, I work for Modality Systems).
