10.1 Fault Symptoms

If any of the following Fault Symptoms occur, follow the instructions below.
Fault
The display stays dark
There is no ring signal
Connected call but no
sound or one way sound
Voice quality is bad
26 June 2012
Probable cause
Low battery level or faulty
VoWiFi Handset.
"Ringer off" icon is on, or
ringer volume is set to
silent, or faulty VoWiFi
Handset.
IP adressing fault, or
muted or bad speaker/
microphone
Increased traffic load or
interference.
Action or comment
Charge the battery. If the VoWiFi
Handset does not work after charging,
contact the system administrator.
Press and hold the Mute key, or
increase volume (in the VoWiFi
Handset, select Settings > Sound &
Alerts > Volume) or contact the
system administrator.
1) Note the IP address of the VoWiFi
Handset. Turn the VoWiFi Handset
off and ping the IP address. If
something is found, the problem is an
IP address conflict.
2) Check if the VoWiFi Handsets are
muted.
3) Use a headset to eliminate bad
speakers/microphone.
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 analyser and look
for non 802.11 interference.
