Fader
The fader control enables the user to add gain or attenuate the telephone signal 
from +20 dB to -100 dB with a resolution of 0.1 dB. This gain is applied in the 
digital domain.
A maximum and minimum gain range can be specified for the faders to limit 
the user gain control. The process of setting the min and max volume controls 
is described in the input fader section.
There is a fader control on the phone input channel and a fader control on the 
phone output channel.
Delay
The delay processing allows the designer to add from 0 to 1000 milliseconds of 
delay on both the telephone input and output channels. While the delay is set 
in milliseconds in the user interface, it can be manually set through the com-
mand API in samples where each sample represents 1/48 of a millisecond.
Telephone Controls
In addition to the audio processing paths described in this section, telephony 
channels have additional user controls to configure the telephone interface. 
Select the Phone Settings... button to get access to the telephony specific 
controls.
