I am trying to use the provisioning in fspbx that is available under Devices. I can see my T33G there with the correct MAC address. However, if I try to change the Device Keys there (Key 2 etc.), it has no effect on the phone. What am I missing?
 
Screenshots of your Device settings with two keys, please, and a screenshot of your Profile for this device showing how you assigned these keys.
 
To have to lines show on the phone you will need to add them to your profile. Here is an example, but adjust it to your needs. My example will put 5 buttons (Line 1) and a few BLF buttons.

Still nothing. If I look at devices, it does not show as being provisioned. Do I need to set something on the phone itself to allow this?

In the documentation I see the following:

What you typically do in the Devices section​

A normal workflow looks like this:

  1. Create a Device
  • Vendor / Model (if applicable)
  • MAC address (most common identifier)
  • Optional: friendly name (e.g., “Front Desk Phone”)
  1. Assign one or more Lines
  • Link the device to an extension (or multiple extensions)
  • Set line positioning (Line 1, Line 2, etc.)
  1. Provision the phone
  • Point the phone to your provisioning URL (or use DHCP option 66, depending on your environment)
  • Reboot the phone so it downloads its config


What is the correct provisioning URL if I use the default locations?
 
In your screenshot, I see that you have not assigned any lines to this device. You need to have at least one.

And yes, you absolutely need to point the phone to the provisioning URL:

Code: 
https://yourdomain.com/app/provision

In the default settings, you also need to set the provisioning username and password.

Code: 
http_auth_username
http_auth_password

Before you point the phone to the provisioning server, you can try to open the URL in the browser and see if it gets generated correctly.

Code: 
https://yourdomain.com/app/provision/44dbd26b55.cfg

Make sure the above URL matches your MAC address.
