In my company we have about 10 Polycom RealPresence Trio 8800 deployed. In the past 2 or 3 months we have been experiencing some Audio performance degradation in about %50 of the conferance meetings. I also noticed that "Low Memory" message is randomly showing up on all of the devices. I've checked every possible option to find is there a way to free up the memory but NO LUCK. I also haven't seen a single article that would mention any "low memory" issues. I tried Facroty Reset of the device but after some time that device also get's the "Low memory" notification.
Tried all avaiable Firmware versions (currently running the newest one on all devices 126.96.36.19917).
Tried installing that firmware via Web UI or USB stick - same results.
I can see in the Logs the low memory message:

Please let me know if there is a way that I could prevent those devices from running out of memory.
PS. removing the logs or logging didn't work - still getting the message about the memory being low.
welcome to the Polycom Community.
The issue is that this is a hosted Office 365 issue where our partner Microsoft is hosting an old withdrawn software.
In order to do this use the Skype for Business Online PowerShell Module as described by my colleague Jeff Schertz => here <= as the EnableDeviceUpdate parameter is set to True by default.
There is a couple of posts already => here <=
You need to disable the software update on the O365 end and manually upgrade as shown => here <=
Btw the current latests software is 188.8.131.5291
