From the Audio screen you can select the Transmission Mode, Server Gain, Bit Rate, and enable or
disable storage of the audio recording.
Transmission Mode

Simplex (Listen only) – The local/remote site can only listen to the other site.

Disable – Select this option to turn off the audio transmission function.
Server Gain Setting
Set the audio input 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), µLAW (G.711) and ALAW (G.711). Both µLAW and ALAW signify 64 kbps, but in different
compression formats. A higher bit rate enables higher audio quality, but requires higher bandwidth.
Note:
Latitude does not support G.726 bit rates.
