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
either a fault has occurred or your infor-
mation was incomplete:
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 modem/Internet connection.
¤
Check whether the phone is connected
to the LAN.
– It may not have been possible to
dynamically assign an IP address to
the phone
or
– You have assigned a static IP address
to the phone that has either already
been assigned to another LAN sub-
scriber or does not belong to the
router's address block.
¤
Find the IP address using the hand-
set menu:
§Menu§
¢
Settings
¢
Base
¢
VoIP Configuration
¢
(enter sys-
tem PIN)
¢
IP Configuration
¢
IP Address
¤
Start the Web configurator with the
IP address (page 46).
¤
If no connection can be established:
change the settings on the router
(activate DHCP server) or the
phone's (static) IP address.
SIP registration failed!
u Your personal data for registering with
the VoIP provider may have been
entered incompletely or incorrectly.
¤
Check your entries for Username ,
Authentication Name and Authentica-
tion Password . In particular, check
your use of upper and lower case.
To do this, open the following menu
on your handset: §Menu§
¢
Settings
¢
Base
¢
VoIP Configuration
u The server address for the VoIP server
has not yet been entered, or has been
entered incorrectly.
¤
Start the Web configurator.
¤
Open Settings
¢
Telephony
¢
VoIP Web page.
¤
Edit the server address where neces-
sary.
You will find other messages and possible
measures in the Questions and answers
section on page 61.
Note:
If port forwarding is activated on your router
for the ports that have been registered as the
SIP port (Standard 5060) 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):

Select IP address type .
Please note that the IP address and subnet
mask depend on the router's address block.
You must also enter the default gateway and
DNS server via the Web configurator
(page 50). The IP address for the router is gen-
erally entered here.
