we just switched a customer to a hosted with yealink t42,t46 and t48 and they are complaining the phones sound muffled, after testing by comparing with a few other phones side by side here at our shop I would have to agree with our customer they sound very muffled and over bass.

Customer wishes they could go back to previous phones but thats not an option.

Has anybody noticed this with yealink phones and come up with a solution ?

Hello, Yes we have run into this same problem with these phones. FYI we have Yealink phones in stock for sale at a very low price. In the past we would roll in good working phones as we have never really tried to diagnose the problem so, I dont have an answer / fix for you other than trying different handsets and or units.

Hopefully one of the guys here on Sundance has a better answer for you! Call or email for quote if you would like, and if we have what you need we can sell to you.

First I would make sure that they are on the latest firmware. Then I would try playing musical handsets and see if that fixes the issue. If all else fails the few times that I have tried contacting Yealink's tech support they seemed responsive.

Have you tried removing g722 as a allowed codex. I normally have to do this on the Panasonic phone system as we had customers complain about the sound on the NT 5xx phones on the NS and found the they didn’t like the high def audio and used to say it was muffled and poor quality

Made g711 first preference and they said it was much clearer. I think it was coming from TDM they just didn’t like the tone of high def

obt, I just tried every codec possible and its muffled on all of them,

I did try different handsets on the yealink phone and some sound better than others but none actually fully work

Who is the Hosted provider.
We use mostly Yealink phones and never had that problem. Never had any system problem. This should be up to the Hosted provider to trouble shot.
