RE: T42G and T48G handset audio problems
Customer has (18) T46G phones, new installation about 45 days ago. Several users are complaining about same problem. I would assume the firmware is current since recently installed. Did this latest firmware v28.81.0.70 come out in the last couple months?
No we didn't factory default the phones.
I can get my tech to check these if you think it will make a difference.

The customer is complaining that they can't understand the caller. Is there any fix for this? I've already contacted tech support/sales engineering at Star2Star and they don't have any fixes.

In short, the audio from the handset/receiver port has the highs muted and the lows accentuated. It makes it hard to understand many people. But, if you plug the handset/receiver into the headset port, you get a very normal sounding audio experience. Both ports should produce the same audio, and it should sound like the headset audio.

How do we get this addressed for the T42G and the T48G?

Hi Mark,

Are all the phones running on the latest firmware v28.81.0.70
http://download.support.yealink.com/down...1.0.70.zip

How many T46G phone does your customer have and how many have this issue?
Did you try to reset the phones to factory default?
