The value is only valid when the interface is off-hook.
pstn_out_gain PSTN Output Gain
Description
This parameter sets the gain (in dB) of the signal going to the PSTN interface.
Equalizer Parameters
Description
The line outputs (both conferencing and sound reinforcement) each have a
graphic equalizer that can have either 10 bands (1 octave), 15 bands (2/3
octave), or 31 bands (1/3 octave).
Most physical channel types have 10 bands of graphic equalization. The
Conference Link input and output physical channel types only have 5 bands
of graphic equalization. The signal generator and AEC reference physical
channel types do not support graphic equalization.
All physical channel types except the signal generator support a high-pass
filter, a low-pass filter, a high-shelf filter, and a low-shelf filter.
