T42G and T48G handset audio problems

[Nimesh]

Hello,

I have 40 T42G's deployed and where this quality issue isn't too big for internal calls (as the codec and clarity is good), when people are talking to external callers via a PSTN gateway, the low treble and high bass is causing a problem especially when talking to male people. The staff are struggling to understand what they're saying.

Initially I was putting the blame on the PSTN gateway but now after reading these comments from people, the phones definitely aren't helping the case.

Reading on the 3CX forum, a modification to an older V80 firmware was done for somebody with satisfactory results - can't the Yealink staff deploy the same fixes to the current latest firmware? 29.81.0.70, as this is the current supported firmware of 3CX. The fix was deployed in version 29.80.0.202.

Otherwise we will have no choice but to move to another phone manufacturer. The department are already testing other phones to see whether clarity can be improved. Personally I like the Yealink phones and would rather we're able to keep them in play.

Thanks.
