T42S +EHS36 + CS54= disconnects and reconnects - Beastorm - 10-13-2021 01:13 AM

Hello,

We have T42S phones with EHS36 and Plantronics CS540 on a 3cx system. We have updated the firmware of the phones to 66.86.0.5 and since that time the headset disconnects and reconnects and even connected we cannot answer or hang up with the headset button.

I did some research that talked about updating the firmware of the EHS36 from only 4 phone models (T26P, T28P, T38G, T46G). I don't have these phone model, is it possible to do it on another model?Otherwise I will have to put an older version of the firmware on the T42S?
