Configuring Noise Reduction

The phone supports a noise reduction mechanism designed to improve call clarity in open-space environments. This mechanism minimizes background noise, such as machinery, chatter, and ambient sounds, heard by remote participants when the local user is not speaking.

By default, the system intelligently suppresses most background noise without compromising voice quality. For high-noise environments, an advanced configuration option is available:

Parameter: dsp/audio/reduce_open_space_noise
Default Value: 2
Optional Value: 3 (for more aggressive noise reduction, with slight impact on voice quality)
