T21 Headset volume problem
Hi,

We have a problem with T21 headset volume level.
Even we set it to maximum level from config.bin, we still cannot hear well enough.
Any suggestions ???

Hi Cangurer,

You can't set it in config.bin file, you have to set it through autoprovision.
This is the autoprovision parameter, default value is 29. It range from 1-53.

voice.headset_send =

Or you can directly use this URL to do an autoprovsion, I have uploaded to a ftp server. It will change the headset send volume to 39.

ftp://James:494qh65Z@ftp.yealink.com/Aut...volume.cfg

Phone will reboot if it's configured successfully.

Regards,
James
