Completing the VoIP settings

Once all the necessary entries have been

made, the handset reverts to idle status.
If all the settings are correct and if the

phone can establish a connection to the

VoIP server, then the internal name of the

handset will be displayed:

You can now use your phone to make calls

via the fixed network and the Internet!

Callers can reach you on your fixed

network number and your VoIP number!

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:

IP Address

Start the Web configurator with the

IP address (page 51).

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!

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:

sary.

Please note:

To ensure that you can always be reached via

the Internet, the router should be permanently

connected to the Internet.

Please 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), see

page 48.
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 54). The IP address for the router is gen-

erally entered here.
