Prevent Polycom Phone rolling back to old version - SFB Online.
Noticed that after the firmware update is installed, Polycom phone rolls back to the previous version automatically.
I got a message on the Polycom Phone that says "there’s a new update available" it then automatically installs the old version."
The IP Phone rolls back to the old version 5.6.0.17325.
To prevent the phone from rolling back to the old version, run the following command after logging into SFB Online through PowerShell.
Set-CsIPPhonePolicy -EnableDeviceUpdate $False
It will take around 20 mins to 1 hr to take effect.
If you just want to prevent a single device from rolling back you can create a configuration (.cfg) file using the below code and then import it onto the phone:
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<PARAMETERS device.set="1" device.prov.lyncDeviceUpdateEnabled.set="1" device.prov.lyncDeviceUpdateEnabled="0" lync.provisionDeviceParams.enabled="0" />

Richard Jenner Thanks, it's instructive info.
Guidance for this is covered in this detailed article:

This does work - but it's worth noting that it is downgrading to the version of the software that Microsoft have currently certified for use with Skype online. It is possible (although unlikely) that you may run into issues running a newer version that the recommended one. Microsoft will eventually certify the newer versions of the software, and at that point your phones should auto-update.
To clarify when an initial X.0 release is officially qualified for SfB then future X.1, X.2, X.3, etc are not re-qualified. These newer releases are always recommended by default but Microsoft does not update the Device Update server for every version.
- Thanks for the clarification! I hadn't realised that point releases weren't automatically pushed
