10.1 Fault Symptoms
If any of the following Fault Symptoms occur, follow the instructions below.
Fault Probable cause Action or comment
The display stays dark Low battery level or
faulty handset.
Charge the battery. If the handset
does not work after charging, contact
the system administrator.

Connected call but no
sound or one way
sound
IP addressing fault, or
muted or bad speaker/
microphone
1) Note the IP address of the handset.
Turn the handset off and ping the IP
address. If something is found, the
problem is an IP address conflict.
2) Check if the handsets are muted.
3) Use a headset to eliminate bad
speakers/microphone.
Voice quality is bad Increased traffic load
or interference.
1) Check if QoS is working in both
directions. Voice traffic should be
prioritized on both the LAN and the
WLAN.
2) Connect to other phones (wired,
analogue or external) to determine if it
is the other end that may cause bad
quality.
3) Do a site survey and check for
areas with under/over coverage and
other interfering 802.11 systems.
4) Do a network performance test to
ensure the wired LAN/backbone has
adequate capacity.
5) Use a spectrum analyzer and look
for non 802.11 interference.
