EHS36 with firmware 4.16.0.0 & T38G

[lorn10]

Here follows a last little statusupdate:

After downgrading to EHS36 firmware v2.16.0.0 the Plantronics CS540 wireless headset has started to work as it should! :-D

So it is exactly as I assumed. There is definitely a compatibility problem with EHS36 firmware v4.16.0.0 in conjunction with older V7x firmware based phones.

Note, - to make a downgrade, the T38G phone has do be set to firmware 38.70.0.162. Only this specific version contains the EHS36 firmware file.

Interestingly I am now on firmware v2.16.0.0 and not v3.16.0.0. So that version seems to be the original one for the Yealink T3x IP phone series.

I have now updated the EHS36 firmware matrix in my previous post.

Kind regards from Central Europe
