We had found the issue from other customers, and trying our best to solve the problem now, but it need sometime.
As I know, the fixed firmware is a temporary soulution, we will solve the issue permanent in official version.
My colleague James is responsible for the problem, and I will contact with him then give you more detail info.

Hi thanks Karl for this , people reported this for around 1 year now and its look like there is a limitation from phone hardware to solve this sound problem , yesterday I tried to factory default my t46g with default provisionning , sound is still muffled and mic caused echo for remote party , I hope than Yealink will find a way to give this series a better frequency tuning , in the meantime I will get the t46g replaced on RMA

Thanks
