Audio Quality
Select this option to set the desired audio standard that will be used to
transmit audio to the remote location. The selections are:
Auto
This setting will instruct the APV200-IP to automatically
(default)
adjust to the best audio available, as determined by the
capability exchange between the local and remote
systems. This is the recommended setting. However,
G.728 is the preferred selection for one- or two-channel
video calls, and G.722 will be selected for three to six
video channel calls.
G.728
This setting should be selected when using the data
ports to exchange data between sites and the best video
quality is required.
G.711
This setting should be selected when the remote site is
known to have only the capabilities of G.711 audio—
typically older systems that have not been upgraded.
G.722-56K
This setting should be selected for best audio quality
when AUTO mode will not negotiate with the remote site
on videoconference calls greater than 128K.
G.722-48K
This setting should be selected when audio quality better
than G.728 is required and AUTO mode will not negotiate
with the remote site on video calls greater than 128K.
