Disconnect the phone from internet (not your network)
Factory reset the phone
Try to log in with admin/admin
If successful, the phone is likely provisioned by Verizon. This can be checked by restoring the internet connection so that the phone can be provisioned and thus the password change.

Well your hunch was correct. I was able to login as admin.
So where does this leave me?
I suppose that Verizon will just undo any settings that I attempt.

A normal or standard procedure is for providers to ensure that telephones are provided with the necessary information so that they will work properly.
They use Remote Provisioning Server for this. When a phone is started it broadcasts its MAC address, on which the RPS will provide the phone with the correct data.

LT;DR Please contact Verizon and ask them to remove the devices from their RPS file server.
The disadvantage is that the devices are no longer provisioned by the provider.
You will now have to do this yourself or by the PBX that is used, but you will still have the option to log in to the device as an admin.

Kind regards,

I am not an employee of Yealink.

Please do not send unsolicited PM messages. I will not answer them.
