Phone firmware won't update


I think it is working because it is taking a long time to come back on line!


I think it was switching to HTTPS due to a setting in your Zero Config. Turning the 3CX option off, turns off Zero Config for the phone.

Remember to turn it back on after you finish upgrading.

I rebooted from the phone’s screen and I still cannot get to the web gui. Time for a factory reset?

Firstly, have you tried to reset your browser window (Ctrl-F5 on Chrome)?

Secondly, has the phone’s IP address changed? Push the up arrow on the phone (navigation controls) to see what the phone’s IP address currently is.

If neither helps, then yes, do a factory reset.


Ok. I can get back into the phone and it still is not updated. It is staying on the http. Is the correct path
