10.2 Display Information
The following error messages can be shown in the VoWiFi Handset display:
Battery life is bad
DTIM might not be set
correctly.
U-APSD is not used.
Cisco/Ekahau location
client settings needs to be
changed.
1) Check “Beacon interval” and
“DTIM” settings in the AP.
2) Verify the coverage, since low
signal strength will make the VoWiFi
Handset to constantly search for
other APs and thereby consuming
more power.
3) Use a sniffer and check the
amount of broadcast traffic that is
transmitted on the WLAN.
4) Check if correct models of the
chargers are used.
5) Verify with another battery.
6) If the system is supposed to use
U-APSD for voice calls check the
voice power save mode parameter
in the PDM.
7) If using Cisco/Ekahau location
client, change the settings.

No access
The VoWiFi Handset is in
range, but has no access
rights.
Handset has found and
associated to the WLAN
(a wireless network with
the configured SSID and
correct security settings).
But it can connect to
neither the gatekeeper
nor the IMS3.
Switch off the VoWiFi Handset and
then switch it on again. If this does
not work, contact the system
administrator.
1) Check if the VoWiFi Handset has
an IP address by entering the
“Network info” screen. If not check
the WEP key if used or WPA/WPA2
passphrase.
2)
If using WEP, double-check the
key if the VoWiFi Handset has no IP
address. If you have a wireless
sniffer, configure it to the correct
key and try to decode packets both
from and to the VoWiFi Handset.
3) Check the Gateway address. Try
to ping the gateway from another
PC.
4) C
heck the IMS3 address. Try to
ping the IMS3 from another PC.
