Hi togeher,
I've just wondered that my Polycom VVX 501 phones with UC 6.0.0 doesn't get any automatic firmware update when provisioned with Genesys Cloud using Cloud Edges.
When I do the firmware update manually to the latest release 6.4.x they are getting downgraded to the currently supported version 6.3.1 by Genesys Cloud without a problem.
Investiating the issue more deeply I've found that the firmware files are hosted at a fileserver with an Amazon CA verified certificate that the phone doesn't trust.
With manually installing the "Amazon Root CA" root certificate to the "Platform CA 2" the phone could get updated from 6.0 to 6.3.1 without any problem.
Now you can just download the device configuration, look for "device.sec.TLS.customCaCert2" and add this certiciate data to your custom provisioning file hosted any any webserver. With additing the path to that file at your Genesys Cloud phone base settings at Provisioning -> Custom Configuration Files your phones are able to get updated automatically.
I hope that this will help you in case your are having the same problem.
BR, Robert
