Description


Some customers are annoyed when they use headphones with Yealink, the other side can’t hear their voice clearly.

Here is the original question from customer:

When I use headphone with Yealink phone, the voice level is really low but when use the same headphone with other brand IP phones, the voice level is normal.


Resolution

Yealink phone have configuration which can adjust the sending volume of currently engaged audio devices (handset, speakerphone or headset) when the phone is in use:

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

#To all phone models with V80or higher firmware, the value range from -50~50, default value is 0.
#To T4x series with V73 firmware, the value range from -120~30, default value is 1.

Note: We recommend that you modify this parameter cautiously. An unreasonable value may render the voice quality bad. If you change this parameter, the IP phone will reboot to make the change take effect.

To old T2x model and T3x, the value can be adjust in web interface-> Setting-> Voice.
For the V80 or higher firmware, the value can be adjust in web interface->Feature->Audio:图片.png
