We have been testing Yeahlink phones but are having problems with the audio quality. Its sounds like you're talking through a sock.
We like the phones but need better call quality.. any ideas?
Hi
To T41, please let the customer upgrade phone to 36.80.0.72 which change handset port voice paramter.

Currenlty there is no such a T48 firmware. If it is confirmed that the firmware 36.80.0.72 solve the issue, we will release a T48G firmware which include same change when T48G V80 sp1(improve bluetooth headset compaility, WIFI feature etc) firmware is finished.
Same problem than us t27, t46 and the same bad sound quality
I also have the same thought.
