No connection to the Internet/VoIP server
If one of the following messages is displayed instead of the internal name after the con-
nection assistant is closed, then either a fault has occurred or your information was incom-
plete:
Server not accessible!
The phone has no connection to the Internet.
¤
Check the cable connection between the base station and the modem/Internet connec-
tion.
¤
Check your router's Internet status:
¤
Start the router Web configurator (page 69).
The Internet Status is displayed on the start screen. If necessary, check the access data
stored in the router (page 71).
¤
Check whether the IP address settings for the base station phone and base station router
are compatible.
Please note the following:
– The IP address for the phone must belong to the address block for the router. For
example:the first three parts of the IP addresses for the phone and the router in sub-
net mask 255.255.255.0 must be identical.
– The IP address for the phone must not be assigned to any other LAN subscriber. If the
DHCP server for the router is enabled, then no static IP address can belong to the
address block that is reserved for dynamically assigning IP addresses (default setting:
192.168.1.100 – 192.168.1.150)
– If the phone is to be dynamically assigned an IP address, then the router's DHCP
server has to be activated.
¤
Find the phone's IP address via the handset menu:

Start the phone Web configurator with the IP address (page 65).
If no connection can be established:
¤
change the settings on the router (activate DHCP server, change DHCP settings, see
¤
activate dynamic assignment of address to the phone (page 60) or
¤
change the phone's (fixed) IP address (page 60).
Recommendation:
You should restart your base station and the connected devices (PC) as soon as you make changes in
your LAN to IP addresses or address blocks. During the restart you should start the base station first
(page 83) and then the connected devices (PC). This will deactivate old IP addresses and force new
dynamic IP addresses to be assigned/requested.
