VoIP – making calls via
the Internet
With VoIP (

nternet

rotocol),
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:

u
Access to the services of a VoIP pro-
vider. Open up to six accounts with
dif-
ferent
VoIP providers.
Gigaset HDSP – telephony
with brilliant sound quality
Your Gigaset S675 IP
supports the broad-
band codec G.722.
With your base sta-
tion and the corre-
sponding handset,
you can thus make calls via VoIP with bril-
liant sound quality (High Definition Sound
Performance).
If you register further broadband-capable
handsets (e.g. Gigaset S67H, S68H or
SL37H) with your base station, internal
calls between these handsets will also be
conducted via broadband.
Preconditions for broadband connections
to your base station are:
u
For internal calls
:
Both handsets are broadband-capable,
i.e. both support codec G.722.
u
For external calls via VoIP:
– You make the call from a broadband-
capable handset.
– You have selected codec G.722 for
outgoing calls (page 102).
– Your VoIP provider supports broad-
band connections.
– The recipient's phone supports
codec G.722 and accepts the estab-
lishment of a broadband connec-
tion.
Please note:
The VoIP service
Gigaset.net
supports broadband connections.
