I was previously using 28.72.0.37 in my T46, which you posted for another user who also had problems with the sound quality.

I recently updated to 28.80.0.70. The sound quality was poor again with this update. So I had to go back the older version. I use a Plantronics headset and Vista amplifier with the phone.

I am puzzled why the sound quality should vary so much from version to version? With the latest firmware the audio has a muffled quality it is hard to explain.

Thanks, T46 Guy
