Making calls with VoIP and
the fixed network
Making an external call
External calls are calls made via the public
telephone network (fixed network) or via
the Internet (VoIP). You can use the talk
key c when dialling to select what type of
connection you want to use (fixed net-
work or VoIP). One particular connection
type is set as the default connection for
your phone. The default is VoIP (for how to
change the setting if required, see
page 41).
¤
Enter the required number/IP address
using the keypad.
¤
Press the talk key c briefly if you want
to make the call via the default connec-
tion.
Or:
¤
Press and hold the talk key c if you
want to make a phone call via the other
connection type (the non-default con-
nection).
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.
P
Press 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 85) to the IP
address (e.g.
149*246*122*28#5060).
Ending a call
a Press 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 37), the handset will take a call
automatically when you lift it out of the
cradle.
Notes:
– 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.
– If you use a different GAP-compatible hand-
set to the Gigaset C45, all calls will be made
via the default connection, even if you
press and hold the talk key
c
. If you want
to use the non-default 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, see
page 56). It will then be inserted automati-
cally for local calls.
Notes:
– Dialling with the directory (page 24) or last
number redial list (page 26) saves repeated
keying of phone numbers.
– You can assign a number from the directory
to a key for speed dialling (page 25).
– 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.
