The volume is turned all the
way down on the monitor or
external audio system.
The system's audio outputs
are not connected properly.
The far site's microphones are
not placed correctly.
The far site's microphone is
not connected or does not

Solution
Look for the far site Mute icon. Ask the
far site to unmute the microphone.
Note: The far site's microphone may be
muted even if you do not see a far site
Mute icon.
Check the monitor's or external audio
system's volume setting. Then check
the system's audio output using the
Speaker Test screen under
Diagnostics > Audio. You should hear
a 400 Hz tone.
Check the system's audio connections
to the monitor, or to the external audio
system if one is connected.
Verify that the system is connected to
the correct audio connectors on the
monitor.
Ensure that each person who speaks is
facing a microphone and is close
enough to it.
Ask the far site to check the cable to the
microphone.
Try the call again later.
Use a different call speed to call the
site, or ask the participants at that site
to call your system at a different call
speed.
Unmute the microphone
Check to be sure the microphone is
installed correctly.
