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 66.82.0.20 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.

Hello Sir,

This is Brian from Yealink Technical Support Team, nice to work with you.

Please provide me the phone MAC address, I will check if the phone is bound to RPS system.

Best Regards
Brian
