RE: "Trusted Certificates" and auto provisioning
I've been struggling with this for ages also. Yes, disabling "Trusted Certificates Only" via the web interface is a workaround, but we wanted a way to provision without touching the devices at all.

The device has an expired ISRG Root X1 certificate. That was updated in firmware V81 but that firmware is not available for the device, as it is too old. I had tried providing the new ISRG Root X1 via RPS' server Trusted Certificate setting, but it still failed. I also tried loading the Letsencrypt R3 + ISRG Root X1 in a single PEM into the base station, and it still failed.

Finally I tried loading those chain certs separately into the base and the ISRG Root X1 cert was rejected with the error "The cert file is prefabricated!". So you cannot override the expired built-in cert.

That discovery finally lead me to a 3CX forum post that provided the solution ... removing the ISRG Root X1 from our provisioning server's chain.pem so that the chain stops at the Letsencrypt R3. Firmware < V81 does not have the R3 cert so you are then able to provide that in RPS as a Trusted Certificate. After doing that, these old devices are able to successfully provision from a factory state, without having to touch them at all.

Since letsencrypt will overwrite the modified chain.pem every 6 months or so when it renews the provisioning server's certificate, we also added static.security.trust_certificates = 0 to the configuration for these legacy devices so that they will not stop provisioning once that chain is reset.
