Silence SuppressionWhen it is set to Default, Silence Suppression allows this 
telephone to operate under system-wide Silence Suppression 
control. For more information on configuring system-level 
settings, see the Help for NBX NetSet > System Configuration 
> System Settings > System-Wide
Choose On or Off to override the System-wide setting. 
Enabling Silence Suppression reduces the number of packets 
transmitted during a conversation. With Silence Suppression 
enabled, when the transmitting telephone sends no packets 
whenever it detects silence in the audio stream, such as a 
pause in conversation.
The receiving NBX Business Telephone generates white noise 
for the periods represented by silence indicator packets. A 
careful listener can notice the difference between generated 
and actual background noise.
Call Record & 
MonitorDetermines the default setting for recording calls made to or 
from this telephone.
■On — Enables recording for all calls to or from this 
telephone.
■Off — Disables recording for all calls to or from this 
telephone.
■Group Default — Uses the setting (either On or Off) for 
the telephone group to which this telephone belongs.
Both the Off and the Group Default settings can be 
overridden. If either telephone in a two-person call or any 
telephone in a conference call has call recording enabled, the 
NBX system enables call recording for the other telephone(s) 
for the duration of the call.
NOTE: If you do not have a call recording license installed, this 
item is not activated (it is grayed out).
