T46G can't disable headset ringer

[mikkelsen92]

Hello,

I am having a weird issue starting with firmware 28.80.0.70 on Yealink T46G.
Previously, when the ringer volume was turned all the way down to mute, the headset would not ring. After updating the firmware, I can't seem to disable the headset ringing at all.

I've tried:
Setting the ringer device to speaker only, no change
Disable headset button on phone, no luck
Multiple identical phones, same issue

If it matters at all, i use Jabra 9460 Pro headsets.

Anyone got any ideas?
Thank you.

EDIT: I found a workaround, I disabled the ringing on the headset by using Jabra Direct.
