Making calls with VoIP and
the fixed network
Making an external call
External calls are those that are made via
the public telephone network (fixed net-
work) or the Internet (VoIP). You can use
the talk key c when dialling to select what
type of connection you want to use (fixed
network or VoIP). One particular connec-
tion type is set as the standard connection
for your phone. The default is VoIP (this
can be changed like other settings if
required, see page 25).
¤
Enter the required number/IP address
using the keypad.
¤
Briefly press the talk key c if you want
to make a call via this default
connection.
or:
¤
Press and hold the talk key c if 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
Via VoIP you can also dial an IP address
instead of a phone number.
¤
Press the star key P to separate the IP
address number blocks from each other
(e.g. 149*246*122*28).
¤
If necessary, press the hash key # to
attach the SIP port number of the per-
son you are calling to the IP address
(e.g. 149*246*122*28#5060).
Ending a call
a Press the end call key.
Answering 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 14), the handset will take a call
automatically when you lift it out of the
charging cradle.
Switching between earpiece and
handsfree mode
¤
Press the handsfree key d to activate/
deactivate handsfree talking during a
call.
If you wish to place the handset in the
charging cradle during a call:
¤
Hold down the handsfree key d while
placing the handset in the charging cra-
dle. If the handsfree key d does not
light up, press the key again.
Please note:
– To make a call in handsfree mode, you can
also press briefly/press and hold the hands-
free key d instead of the talk key c.
– If you use a different GAP-compatible hand-
set to the Gigaset C45, all calls will be made
via the standard connection, even if you
press and hold the talk key c . If you want
to use the non-standard connection to
make a call, enter a star (*) at the end of
the number.
– If you use VoIP to make a call to the fixed
network, you may also have to dial the area
code for local calls (depending on the VoIP
provider). You can avoid this by entering
the area code in the configuration of the
base station (via the Web configurator). It
will then be inserted automatically for local
calls.
