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 during a call can be

done only while in an H.320 call. No changes can be made

while in an H.323 call.
