If one of the following messages is
displayed instead of the internal name
after the connection assistant is closed,
then a fault has occurred:
Server not accessible!
The phone has no connection to the
Internet.
Check the cable connection between
the base station and the router (the
LED on the base station must light up)
and the connection between the router
and the Internet connection.
Check whether the phone is connected
to the LAN. It might not have been
possible to assign an IP address to the
phone or the IP address has already
been assigned to another LAN sub-
scriber and cannot be changed.
Find the IP address using the handset
menu:
v
¢
Ð
Settings
¢
Base
¢
Local Network
Start the Web configurator with the
IP address.
If no connection can be established,
change the settings on the router
(activate DHCP server) or the
phone’s IP address.

Please note:
If port forwarding is activated on your router
for the ports that have been registered as the
SIP port (Standard 5600) and the RTP port
(Standard 5004), then it makes sense to
switch off DHCP and assign the phone a static
IP address (otherwise you may not be able to
hear the other party during VoIP calls):
– Via the handset menu:
