10.5. Audio (Audio and Bit Rate Settings)
The audio setting page is shown below. In the Audio page, the Administrator can select one transmission mode
and the audio bit rate.
Transmission Mode :
- Full-duplex (Talk and Listen simultaneously):
In the Full-duplex mode, the local and remote sites can communicate with each other simultaneously, i.e. both
sites can speak and be heard at the same time.
- Half-duplex (Talk or Listen, not at the same time):
In the Half-duplex mode, the local/remote site can only talk or listen to the other site at a time.
- Simplex (Talk only):
In the Talk only Simplex mode, the local/remote site can only talk to the other site.
- Simplex (Listen only):
In the Listen only Simplex mode, the local/remote site can only listen to the other site.

Select this item to turn the audio transmission function off.
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 :
The selectable audio transmission bit rates 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. A higher bit rate signifies a higher audio quality and requires a bigger bandwidth.
Click on “Save” to confirm the setting.
