T23G too much bass
Hi,

I have over 30 T23G phones, all have a problem with the sound quality, too much bass Sad

Firmware Version 44.81.0.70
Hardware Version 44.0.0.16.0.0.0
I also tested 44.81.0.110

How to fix it ?

Sorry for my English.
Greetings from Poland.

RE: T23G too much bass
Hi,

Please try next options to reduce or solve this issue.
1. Reset the phones to factory default, then auto provisioning without next three parameters: voice.handfree_send, voice.handset_send and voice.headset_send.
2. Make sure the ECHO parameters “ECHO, VAD and CNG” are Enabled.
3. Configure the G722 as default priority codec. (both T23G and PBX side)

Hope this helps.

Best regards,
Frank.

Did you try the options I gave you?
Factory default, ECHO enabled and select G722 codec?????
You should do something, it will not go away by itself.

Best regards,
Frank.

RE: T23G too much bass
I forgot to turn on g722 in pbx Blush
It is much better, but there is still too much bass in the handset.
How to lower the bass on the microphone in the handset ?

Thank you complex1

As far as I know is this not possible, because there are no bass/treble parameters available.
What you can try more is to disable all codecs on the phone, except the G722 codec, so the PBX and phone can’t negotiate about the use of a other codec than the G722 codec.

Hope this helps.

Frank.
