I am using a Polycom VVX 400 running 18.104.22.168.325.
My VVX 400 receives the correct VLAN ID via DHCP Option 129 and the Provisioning Server URL via DHCP Option 66.
I have been experimenting with the two values below in the provisioning file of my 3cx server:
I noticed that some changes on the provisioning file are actually applied on the Polycom phone only after a factory reset, and not after a reboot or after I trigger a re-provisioning (via a check-sync event).
The scenario is the following:
1. Factory reset Polycom
2. <device.net device.net.cdpEnabled.set="1"> and <device.net device.net.cdpEnabled="0">
3. After the initial provisioning-configuration, my VVX 400 has CDP set to "Disable". So far so good.
4. I change some setting on the provisioning file (MAC.cfg) on the server, so now we have:
5. Reboot the VVX 400. What i would expect, is that after the reboot the VVX 400 will request the provisioning files, ignore the CDP value (since <device.net device.net.cdpEnabled.set="0">) and use its default value for CDP, which is 1 / Enabled. But still, CDP remains disabled.
I tried the exact same steps for another value, <reg.1.lineKeys="4"> and the VVX 400 actually applied that value. Instead of registering the same extension once, it registered it 4 times. But it seems to ignore the values it receives for CDP, from time to time.
As per the UC 5.6.0 admin guide, Device Parameters, page 210:
"Note that some parameters may be ignored. For example, if DHCP is enabled, it will still override the value set with device.net.ipAddress"
I am wondering if CDP is one of those parameters, or if something else happens.
Any ideas what is going on?

Resolution: Please check => here <=
Any device.X parameter combination requires at least at one point to have set the device.set="1" or it will not work.

Thank you for your prompt response Steffen.
Yes, this answer was actually the solution.
Please let me elaborate:
After the factory reset, the VVX 400 received the following parameters:
<device.net device.net.cdpEnabled.set="1"> and <device.net device.net.cdpEnabled="0">
This forced the VVX 400 to set CDP to Disable.
During the next provisioning, it received <device.net device.net.cdpEnabled.set="0"> from the configuration server.
It makes more sense that in such case the VVX 400 keeps the previous value (CDP=0) than the default (CDP=1) which I would expect, this is why its value was not changed.
