Version 4, 16.09.2005
Safety precautions
Please note:
Read the safety precautions and the user guide before use.
Explain their contents to your children, and the potential hazards associated with using the tele-
phone.
Only use the mains adapter supplied, as indicated on the underside of the base station.
Fit only the recommended rechargeable batteries (page 58) of the same type! This
means: do not use any other battery type or non-rechargeable batteries as this could
result in significant health risks and personal injury.
Insert rechargeable batteries with the correct polarity, and use them according to this user
guide (polarity symbols can be seen in the handset's battery compartment, page 6).
The operation of medical appliances may be affected. Be aware of the technical condi-
tions in your particular environment, e.g. doctor's surgery.
Do not hold the rear side of the handset to the ear when it rings or when you have acti-
vated on the handsfree function. Otherwise you risk serious and permanent damage to
your hearing.
The handset may cause an unpleasant humming noise in hearing aids.
Do not install the base station in bathrooms or shower rooms. The handset and base sta-
tion are not splashproof (page 54).
Do not use your phone in environments with a potential explosion hazard (e.g. paint
shops).
If you give your Gigaset to someone else, make sure you also give them the user guide.
All electrical and electronic products should be disposed of separately from the municipal
waste stream via designated collection facilities appointed by the government or the local
authorities.
This crossed-out wheeled bin symbol on the product means the product is covered by the
European Directive 2002/96/EC.
The correct disposal and separate collection of your old appliance will help prevent poten-
tial negative consequences for the environment and human health. It is a precondition for
reuse and recycling of used electrical and electronic equipment.
For more detailed information about disposal of your old appliance, please contact your
local council refuse centre or the original supplier of the product.

Gigaset C460 IP – more than just making calls
Gigaset C450 IP / GBR PTT / A31008-M1713-L151-1-7619 / starting.fm / 15.5.06
Version 4, 16.09.2005
Gigaset C460 IP –
more than just making calls
Your phone lets you make calls both via
the fixed network and (cost effectively)
via the Internet (VoIP) without using a
PC. It is secured against Internet viruses
by its own network interface with pro-
tected operating system.
And your phone can do much more
besides:
uBy registering a second handset to your
base station, you can use one handset
to make a call via the fixed network and
the other to make a call via the Inter-
net.
uConfigure the phone connection for
VoIP without a PC. Your phone's con-
nection wizard downloads general data
about your VoIP provider from the
Internet and guides you through enter-
ing your personal data (account). This
makes it easy for you to start using VoIP
(page 10).
uIf necessary, establish any further
required VoIP settings on a PC. The
phone has a Web interface (Web con-
figurator) that can be accessed via
your PC's Web browser (page 43).
uAssign your own password (system
PIN) to protect your device and the Web
configurator from unauthorised access
(page 38).
uYou can operate your phone behind a
router or a switch (depending on your
provider). To operate behind a switch,
you may need a firmware update from
the Internet.
uSend and receive SMS messages via the
fixed network (page 26).
uSave 100 phone numbers on your
handset (page 22).
uYou can programme the keys of your
phone with important phone numbers.
The phone number is then dialled by
simply pressing the respective key
(page 23).
uUse the handsfree function to keep
your hands free when making a call
(page 17).
uUse your handset as an alarm clock
(page 37).
Have fun using your new telephone!
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:
uYou can make cost-effective calls with
high voice quality with subscribers on
the Internet, the fixed network or the
mobile phone network.
uYour 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:
uA broadband Internet connection (e.g.
DSL) with flat rate or volume-based
price
uInternet 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:
http://siemens.com/gigaset
uAccess to the services of a VoIP pro-
vider. Open an account with a VoIP pro-
vider.

Connecting the charging cradle
Connecting up the charging cradle and
mounting it on the wall (if required) is
described at the end of this user guide.
¤To charge the batteries, leave the hand-
set in the charging cradle.
For questions and problems see page 54.
Initial charging and discharging of
batteries
Battery charging is indicated in the top
right of the display by a flashing battery
icon e, Vor U. During handset
operation, the battery icon indicates the
charge status of the batteries (page 1).
The correct charge status can only be dis-
played when the batteries are first fully
charged and discharged through use.
¤To do this, leave the handset in the
charging cradle without interruption
until the battery icon stops flashing in
the display (approx. 13 hours).
¤Once the batteries are fully charged,
remove the handset from the charging
cradle and do not put it back again until
the batteries are fully discharged.
Please note:
uAlways repeat the charging and dis-
charging procedure if you remove the
batteries from the handset and insert
them in again.
uThe batteries may warm up as they are
charging. This is not dangerous.
uAfter a while the charge capacity of the
batteries will decrease for technical
reasons.
Please note:
– Only place the handset in the charging cra-
dle that is intended for it.
– If the handset has switched itself off
because the batteries are flat and if it is
then placed in the charging cradle, it will
switch itself on automatically.
Please note:
After the first battery charge and discharge,
you may replace your handset in the charging
cradle after every call.
Please note:
You will find explanations for the symbols and
typographical conventions used in this user
guide in the appendix, page 54.

For many VoIP providers, the connection
wizard downloads the general settings
directly from the Internet. If your provider
settings are not available for download,
you must enter the data manually via the
Web configurator (page 47).
Starting the connection wizard
Precondition: You have connected the
base station with the mains power supply

charged, the message key on the handset
will flash (around 20 minutes after you
have put the handset in the charging cra-
dle). Press the message key to start the
connection wizard.
If the connection wizard starts automati-
cally, a prompt will be displayed:
§Yes§ Press the display key to con-
firm the prompt.
Make the VoIP settings with the help of
the connection wizard.
Making VoIP settings
Precondition: The base station is con-
nected to the Internet, i.e. the base sta-
tion is connected to the router and the
router has an Internet connection
(page 9).
Downloading VoIP provider data
qSelect country and press §OK§.
qSelect VoIP provider and press
§OK§.

Please note:
Your phone is preconfigured for dynamic
assignment of the IP address. In order for your
router to "recognise" the phone, dynamic IP
address assignment must also be activated on
the router, i.e. the router's DHCP server is acti-
vated. Turn to page 40 to find out how to
assign your phone a static IP address if neces-
sary.
Please note:
The connection wizard will also start automat-
ically if you try to establish a connection via
the Internet, before you have made the neces-
sary settings.
You can also call up the connection wizard at
any time via the menu (page 39).
Please note:
If the data for your VoIP provider is not availa-
ble for download, you can make the necessary
settings with the Web configurator (page 47).
Please note:
To ensure that you can always be reached via
the Internet, the router should be permanently
connected to the Internet.

stant companion both inside the building
and in its immediate vicinity.
Attaching the belt clip
There are notches for attaching the belt
clip on the side of the handset at approxi-
mately the same height as the display.
¤Press the belt clip onto the back of the
handset so that the protrusions on the
belt clip engage with the notches.
Connection socket for headset
You can use headsets with jack connec-
tors. The following models have been
tested and are therefore recommended:
HAMA Plantronics M40, MX100 and
MX150.
The transmission quality of other models
cannot be guaranteed.

Making calls
Making an external call
External calls are those that are made via
the public telephone network (fixed net-
work) or the Internet (VoIP). You deter-
mine what type of connection you want to
use when you dial.
If you want to call a fixed-network sub-
scriber via VoIP, you must always dial the
number with the dialling code.
~c Enter number/IP address and
briefly press/press and hold
the talk key.
The type of connection is determined by
whether you press the talk key c briefly
or press and hold it, i.e. you indicate
whether you want to make a call via the
fixed network or VoIP.
Selecting the connection type
A default connection is established on
your phone (fixed network or VoIP).
¤Press the talk key cbriefly if you want
to make the call via the default connec-
tion.
¤Press and hold the talk key cif you
want to make the call via the other con-
nection type.
Cancelling the dialling operation
You can cancel the dialling operation with
the end call key a.
Entering an IP address
If you are making a call via VoIP, you can
enter an IP address instead of a phone
number.
PPress the star key to separate
the parts of the IP address
(e.g. 149*246*122*28).
#If necessary, press the hash
key to attach the SIP port
number of the person you are
calling (page 75) to the IP
address (e.g.
149*246*122*28#5060).
Ending a call
aPress the end call key.
Accepting a call
The handset indicates an incoming call in
three ways: by ringing, by a display on the
screen and by the flashing handsfree key
d.
You can answer the call by:
¤Pressing the talk key c.
¤Pressing the handsfree key d.
If the handset is in the charging cradle and
the Auto Answer function is activated
(page 35), the handset will take a call
automatically when you lift it out of the
cradle.
If the ringtone is intrusive, press
§Menu§ Silent. You can accept the call so long
as it is displayed on the screen.
Please note:
If there are at least two handsets registered to
your base station, you can use one to make a
call via the fixed network and the other to
make a call via the Internet (VoIP) at the same
time.
Please note:
You can change the setting for the default con-
nection type (fixed network or VoIP)
(page 38).
Please note:
– Dialling with the directory (page 22) or last
number redial list (page 23) saves repeated
keying of phone numbers.
– You can assign a number from the directory
to a key for speed dialling (page 23).
– You can edit or add to any phone number
selected by means of quick dial or from the
directory and use it for the current call.
