Howto:Adjust Speaker volume on IP241 IP222 IP232

Applies To

DHSG and USB Headsets on IP241, IP222, IP232 with V9 and above

Problem

Headsets from different manufacturer respond different (too loud or too quiet) on the default volume setting at the USB or DHSG Ports.

Summary

It's possible to turn down or turn up the volume individual within the phone configuration. The values are -offset-, which means that 0 ist not off, it's the default value of the firmware.

Example to turn up the speaker volume a bit:

  http://ip-adress-of-the-phone/!config change AC-DSP0 HEADSET /mic-volume 0 /spk-volume 2
  http://ip-adress-of-the-phone/!config activate

Example to turn up the speaker volume a bit more:

  http://ip-adress-of-the-phone/!config change AC-DSP0 HEADSET /mic-volume 0 /spk-volume 4
  http://ip-adress-of-the-phone/!config activate

To avoid hearing damage, please be careful with the values! Increase the values step by step. You hear the difference after the !config activate

Example to turn down the speaker volume a bit:

  http://ip-adress-of-the-phone/!config change AC-DSP0 HEADSET /mic-volume 0 /spk-volume -2
  http://ip-adress-of-the-phone/!config activate

If you satisfied with the settings, type:

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

Now, the values are in the config.

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.

In this case it's necessary to do the steps again.
