Firmware keeps downgrading
Hey guys,
Here is the story:
I am trying to get some yealink t46 handsets working. However as soon as I plug them into a network with internet connection they keep downgrading the firmware. New out of the box they come the 66.84.XX.XX but as soon as i connect it to the network it comes up and says firmware upgrading and then once that finished it has the firmware on it. Which is not compatible with the system I am trying to set it up with (3cx)

What I've tried
Ive tried factory resetting and re installing new firmware and nothing. It does the same thing I stays on the newer firmware until its connected to network.
