VoIP – Making calls via the 
Internet
With VoIP (Voice over Internet Protocol), 
your calls are not made via a fixed connec-
tion as in the telephone network, but 
rather they are transmitted via the Inter-
net in the form of data packets. 
You can take advantage of all the benefits 
of VoIP with your phone:
u You can make cost-effective calls with 
high voice quality with subscribers on 
the Internet, the fixed network or the 
mobile phone network. 
u Your VoIP provider will give you a per-
sonal number, with which you can be 
reached from the Internet, the fixed 
network and any mobile phone net-
work. 
To be able to use VoIP, you need the fol-
lowing: 
u A broadband Internet connection 
(e.g. DSL) with flat rate or volume-
based price.
u Internet access, i.e. you need a router 
that will connect your phone to the 
Internet. You can find a list of recom-
mended routers on the Internet at:

u Access to the services of a VoIP pro-
vider. Open an account with a VoIP pro-
vider.
