Upgrade firmare for Yealink T42S, T46S etc.

Yealink has a great dual connect headset (WH63) that can flip between deskphone and softphone/computer. https://www.yealink.com/product/headset-wh63 Unfortunately, it is not compatible with Ring Central because Ring Central's firmware for the Yealink phones is outdated. This was my message to Yealink after hours of figuring this out.

Is it possible to push/help Ring Central to update their auto-provisioned Firmware to V86 for the T42S and T46S Yealink Phones? If I update my T42S/T46S handset firmware to V86 so that I can use your WH63 headset, their settings will downgrade the firmware back to V81 and thus the headset is unusable.

However: https://support.ringcentral.com/article/Deskphones-Latest-Firmware-Versions (showing they are at V81)

i can manually provision my Yealink deskphone to keep the V86 firmware and the WH63 works great! However, when manually provisioned, I lose many Ring Central features. Thus I have downgraded to V81 and cannot use the WH63 headset.

I would think you would sell 1000s more of these headsets if they were compatible with Ring Central (and have 1000s fewer returns and tech support calls). However, the WH63 simply is not.
