Server Gain Setting
Set the audio input/output gain levels for sound amplification. The audio gain
values are adjustable from 1 to 6. The sound will be turned off if the audio gain is set
to “Mute”.
Bit Rate
Selectable audio transmission bit rate include 16 kbps (G.726), 24 kbps (G.726),
32 kbps (G.726), 40 kbps (G.726), uLAW (G.711) and ALAW (G.711).
Both uLAW and ALAW signify 64 kbps but in different compression
formats. Higher bit rate will let higher audio quality and require bigger
bandwidth.
