Audio Quality
The
Audio Quality Preference
screen (
System Info > Admin
Setup
> Video Network
> IMUX > Audio Quality
) allows the
selection of an audio protocol. G.722 audio delivers a higher quality
of audio than G.728 and uses 48 Kbps of the call bandwidth. G.728
delivers telephone quality audio and only uses 16 Kbps of the call
bandwidth. G.728 is generally used for lower data rates.
To set the audio protocol, use the
+
and
-
zoom buttons on the
remote control to move the slider.
Note
Changing the audio quality preferences in a call can only be
done in an H.320 call. No changes can be made while in an
H.323 call.
