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 46).
¤
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 93) to the IP
address (e.g.
149*246*122*28#5060).
Ending a call
a Press the end call key.
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.
– 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 64). It will then be inserted automati-
cally for local calls.
Please note:
– Dialling with the directory (page 29) or last
number redial list (page 31) saves repeated
keying of phone numbers.
– You can assign a number from the directory
to a key for speed dialling (page 30).
– 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.
