conferences, this option also includes the participants who
have to wait for the operator's assistance to connect to the

Asked Question Participants who are waiting in the Q&A queue.
Noisy Line Participants whose audio channel is detected as noisy. The

line can be caused by a variety of sources ranging from
background noise, faulty equipment and noises emanating
from the line itself.
Note: The Noisy Line Detection feature is enabled/disabled
in the "system.cfg" by defining the detection sensitivity.
