T21P Headset audio problem

[James_Yealink]

Hi Joao,

Please just retain these parameters in your cfg file and try again.

#!version:1.0.0.1

voice.handfree_send = 50
voice.handset_send = 50
voice.headset_send = 50

If it doesn't take effect please export your config.bin file, we will check whether the parameter is configured successfully.
We have not only one distributor in Brzail, you can direcltry ask your vendor for the contact of your distributor and contact them.

Regards,
James
