Before we replaced all of them at one of our contracts recently, there was something to do with having to change from https to http in a setting in the phone. I dont recall, and it was stupid. They changed all the phones to a different brand and the problems went away. This was between yealinks and goto jive or whatever it's called now. Packet captures showed that even with all things the same, the phones would have different helo types.
My guess is the chinese guy in charge of the iot botnet got the Rona and hasnt been maintaining the yealink C&C correctly. Probably has long covid and the brain fog.
