In older Snom Versions, it was possible to adjust the microphone volume. This manual adjustment is no longer possible on the Snom Phones.

The settings:

  • Casing Mic Volume / vol_speaker_mic
  • Handset Mic Volume / vol_handset_mic
  • Headset Mic Volume / vol_headset_mic

were discontinued in 2013 due to a hardware platform change.

The new platform no longer supports the interfaces required for the settings.

Instead the system uses an integrated AGC (automatic gain control) which dynamically and automatically controls the gain.

There is no possibility to influence the AGC, so the settings became ineffective and thus they were removed.

Due to the use of the new technology, there is no need to adjust the microphone volume, as it is now optimized fully automatically.
