Listening Volume
Encryption
(IP Only)
To adjust the volume the participant broadcasts to the
conference or the volume the participant hears the
conference, move the slider; each unit represents an
increase or decrease of 3 dB (decibel). The volume
scale is from 1 to 10, where 1 is the weakest and 10
is the strongest. The default connection value is 5.
Select whether the endpoint uses encryption for its
connection to the conference.
Auto (default setting) indicates that the endpoint will
connect according to the conference encryption
setting.
Encryption is not supported in ISDN/PSTN calls.
ISDN/PSTN participants can connect to encrypted
conferences only if the system flag is set to allow
non-encrypted participants to connect to encrypted
conferences.
AGC AGC (Auto Gain Control) mechanism regulates noise
and audio volume by keeping the received audio
signals of all participants balanced. Select this check
box to enable the AGC mechanism for participants
with weaker audio signals.
Note: Enabling AGC may result in amplification of
background noise.
