Presently 21 is the default. Decreasing the value by 4 decreases the sensitivity by 6 dB. The allowed range of the ADC_Gain parameter is 0..31. The same command can be applied for speakerphone mode with name SPEAKER instead of HANDSET.

Different behaviours had been encountered for the microphone sensitivity of USB headsets that may need gain adjustment in the IP112 settings. Therefore a same Web page has been added on IP112 than on IP222 with version 12r2 SR11 and 12r1 SR19. Now it's possible to offset up or down the volume individually within the phone configuration. The value is an ''offset'', which means that 0 is not off, it's the default value of the firmware.

You can set the speaker volume /spk-volume and the microphone volume /mic-volume. Normally the headsets microphone volume must not be changed, because the user adapts the loudness of his own voice from situation to situation. The common problem is the speaker volume.

Please also note, that it's possible for future DSP code updates, that the default value can be changed (what means that "0" can be louder or quieter) and it's possible that updates of the headset manufacturer can change the volume, too.
Note: the same adjustment is available for the handset microphone in case a headset has been plugged that replaces the handset.
So after doing a firmware update on the phone or on the headset, it's necessary to do the steps above again.

Tweaking internal gains in the audio processing chain of the IP111 and IP112 is considered harmful because it assumes a fixed implementation. But the implementation cannot be kept static and may need changes at any time. Therefore support for these parameters is ceased. Please open a support ticket if your environment needs special audio considerations.

Adjusting the headset microphone gain

Different behaviours had been encountered for the microphone sensitivity of USB headsets that may need gain adjustment in the IP112 settings. Therefore a same Web page has been added on IP112 than on IP222 with version 12r2 SR11 and 12r1 SR19. Now it's possible to offset up or down the volume individually within the phone configuration. The value is an offset, which means that 0 is not off, it's the default value of the firmware.

The headset sensitivity can be adjusted with 

  http://addr/dsp.xml

-> Volume

On the browser prompt, the same can be achieved via command 

config add AC-DSP0 HEADSET /mic-volume

The default is restored by a corresponding 

config rem AC-DSP0 ...

command.

Example to offset down the microphone sensitivity a bit: 

  http://ip-adress-of-the-phone/!config add AC-DSP0 HEADSET /mic-volume -6
  http://ip-adress-of-the-phone/!config activate

Example to offset down the microphone sensitivity a bit more: 

  http://ip-adress-of-the-phone/!config add AC-DSP0 HEADSET /mic-volume -12
  http://ip-adress-of-the-phone/!config activate

You hear the difference after the !config activate
Valid values are between -18 and +18, out of range values will be converted to the higher limit.

Example to restore default behaviour: 

  http://ip-adress-of-the-phone/!config rem AC-DSP0 HEADSET /mic-volume 
  http://ip-adress-of-the-phone/!config activate

If you are satisfied with the settings, type: 

  http://ip-adress-of-the-phone/!config write

Now, the values are in the config.

Note: the same adjustment is available for the handset microphone in case a headset has been plugged that replaces the handset.
