We have a problem with a large number of CX5000's where the devices work for a period of time after powering on but then after a random period of time (hours or sometimes days) the microphone stops working. The user will typically connect their laptop to the CX5000 and join a Lync 2013 call, the video works fine and we can hear the remote party but they cannot hear us. Power cycling the CX5000 solves the problem for the next few hours/days.
The organisation has 300 - 400 of these devices deployed globally and reports problems from all offices.
There is a mix of HD and SD devices and all have the latest available firmware installed (1.6.5 - HD, 1.5.5029 SD)
We have tried factory resetting the devices and then re-installing the latest firmware but the problem still occurs.
I have heard through Polycom Support that this problem is affecting at least one other Enterprise customer, is anyone else seeing the problem?
Its proving very difficult to diagnose the problem due to the lack of logging available. As we make any progress I'll post back updates but if anyone else has seen this problem too it would be good to understand if you resolved it.
Thanks
