T21P Low headset volume
Hi,

I have bought 50 T21P phones

Firmware Version: 34.72.0.75
Hardware Version: 34.1.0.0.0.0.0

All of them have a headset volume level problem. The audio is too low.
I found all this threads with similar problems.

http://forum.yealink.com/forum/showthread.php?tid=3242
http://forum.yealink.com/forum/showthread.php?tid=1507

No solution at all.

I'm hoping that some of the forum have solved.

RE: T21P Low headset volume
Hi,

Have you adjusted the headset sending volume following the http://forum.yealink.com/forum/showthread.php?tid=3072?
If yes, could you please export your phone config.bin file so we can check whether this value has been changed successfully?

Thank you!
Regards,
Peter

RE: T21P Low headset volume
Hi Peter.

Thank you for your quick reply.

I changed the y000000000034.cfg file like folowing and start autoprovision.
The config.bin file is attached.

####################################
## Volume ##
####################################
voice.handfree.spk_vol =
voice.handfree.tone_vol =
voice.handset.spk_vol =
voice.handset.tone_vol =
voice.headset.spk_vol = 53
voice.headset.tone_vol = 53
voice.ring_vol =
voice.group_spk_vol = 53

### Only T28P/T26P/T22P/T20P Models support the three parameters
voice.handfree_send =
voice.handset_send = 53
voice.headset_send = 53

Thanks again.
Ricardo Matuda.
