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