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 in
high voice quality with callers on the
Internet, the fixed line network or the
mobile phone network.
u
VoIP providers will give you personal
numbers, with which you can be
reached from the Internet, the fixed
line network and any mobile phone
network.
To be able to use VoIP, you need the
following:
u
A broadband Internet connection
(e.g. DSL) with flat rate (recom-
mended) 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 recommended
routers on the Internet at:

care
Here, go to the FAQ page and select
your Gigaset IP phone. Search for
"Router", for example.
u
Access to the services of a VoIP pro-
vider. Open up to six accounts with dif-
ferent VoIP providers.

capable handset.

outgoing calls (page 117).

band connections.
