EHS Firmware Downgrade
Hey Yealink

I read in this thread that EHS36 can be downgraded with Firmware. The problem is that this firmware only works on T26P, and I have a T28P, T41P, T42G, T46G and T48G.

Does it exist for other phones than T26P?

Our Plantronics headsets works with both EHS and, but with the version the headset does not recognize when the Yealink wants to make a call, so it doesn't activate it's sound and microphone.

You have to press the "pick up" button to get sound through, and then dial the number.

Using the EHS box it automatically recognized that when we were pressing buttons on the yealink, it should activate sound and microphone
