Distorted Audio
Poor audio quality may result from a bad network connection. Ensure that your network
connection is capable of handling the correct bandwidth; LifeSize recommends that your
network connection be capable of at least 100Mbps (100-baseT) for best performance.
Also ensure the loudspeaker is not obscured or damaged at either end of the call. Do not
stack items on top of the phone. Ensure both ends are not muted. Verify that the Audio Out
cables are properly connected to the display and that any external speaker systems are
powered and configured correctly. If an external speaker system has its own volume control,
adjust the volume to near maximum (in the range from 7-10) on the LifeSize audio output
and adjust the volume control on the external speaker system for the best results.
Power and Connectivity Issues
Network status is indicated at all times in the bottom right corner of the screen by the
following icons:
When you place a call, the Call Status dialog displays, indicating the current state of the call
(such as dialing, ringing, connected, answered, etc.). The state of a call is also indicated in
the Call Manager dialog.
If a call does not successfully connect, verify that you have dialed a working number and
that the far end destination is powered on and available. Verify that network settings are
appropriate.
When placing a call using an IP address, if you experience one way audio or video, contact
your network administrator to make sure that the IP address you are using has access to
open network ports 1024 to 66536 to ensure that video and audio traffic is available.
Performance Issues
If you are experiencing performance issues, unplug the display and plug it back in. If an error
message displays, indicating you are using an unsupported monitor, connect to a different
display with a supported resolution. Refer to the LifeSize Room Release Notes for a list of
supported displays with this release.
