No connection to the Internet/VoIP server
If one of the following messages is dis-
played 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 Inter-
net.
¤
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 pos-
sible 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 hand-
set menu:
¢
v Ð
Settings
¢
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.
Provider registration failed!

The server address for the VoIP server
has not yet been entered, or has been
entered incorrectly.

Edit the server address if necessary.
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):

Please note that the IP address and subnet

You must also specify the default gateway and
DNS server. The IP address for the router is
generally entered here.
