I want to change the logging level to show more detail in the boot log of a Polycom VVX311. It currently shows no useful information.

In the web interface under Settings > Logging > Module Log Level I've changed some modules to debug level (for example DHCP Client and DNS) but these changes are not taking affect when the phone reboots. I know changes made via the web interface are stored in a <MAC Address>-web.cfg file which should take precedence over the config from the provisioning server. According the following article:

Deskphones - Polycom | Troubleshoot VVX 300, 310, 400, and 410 issues

https://support.ringcentral.com/article/5138.html

"If the provisioning server permits uploads, these override settings will be saved in a file called <MAC Address>-web.cfg and <MAC Address>-phone.cfg on the provisioning server as well as in the phone’s device settings."

Does RingCentral permit uploads? Note that this is a self-provisioned phone that wasn't acquired through RingCentral. Does that matter in this case? Ultimately, how can I get these log setting changes to take affect when the phone reboots?
