T48G Invalid Certificate
I continue to have problems with one of our T48G devices, using 3CX.
Have done several hard reboots, using latest firmware.

1) Before provisioning with 3cx, I can get in to the device with browser and admin username/password. First thing I do is disable Trusted Certs, because other devices worked when I disabled this (wondering if this is related to the Symantec CA Cert non-trust issue).

2) Then I reboot again, and 3cx shows new device. Assign an extension to the device, and then click provision.

3) Device reboots, but when I click on Phone UI button in 3cx, I get the message in the screenshot, attached, when I use FF. Opening up Chrome and going to the IP of the phone, without https gets me to a log in screen, but username/password won't work, either default or what is shown in 3cx. Then it locks me out.

4) Wondering if the device is defective? Can the firmware be reinstalled, and if so, how?

Thanks, I really frustrated with this! Confused
