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 determine what
type of connection you want to use when
you dial.
Use the talk key to select the type of
connection and make the call
~ c
Enter number/IP address and
briefly press / press and hold
the talk key.
A default connection is established on
your phone (fixed network or VoIP,
page 65).
¤
Briefly press the talk key
c
if you
want to make a call via this default con-
nection.
¤
Press and hold the talk key
c
if you
want to make the call via the other con-
nection type.

The number will be called via the selected

Entering an IP address
You can also dial an IP address instead of a
phone number using VoIP.
¤
Press the star key
*
to separate the
sections of the IP address
(e.g. 149*246*122*28).
¤
If necessary press the
#
key to attach
the SIP port number of the person you
are calling to the IP address (e.g.
149*246*122*28#5060).
Please note:
– You can use your base station to make two
simultaneous external calls (on two hand-
sets): two calls using VoIP or one call each
using VoIP and fixed network.
– You can define which of your VoIP phone
numbers (VoIP account) are used for outgo-
ing external VoIP calls via the handset
( Number Assignment , page 93).
– 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 also enter the dialling code in
the configuration so you do not always
need to enter it for local calls (
Dialing Plans
,
page 94). It will then be inserted automati-
cally for local calls.
Please note:
If you use a different GAP-compatible handset
to the Gigaset S45, 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.
Please note:
– Dialling with the directory (page 34) or last
number redial list (page 37) saves repeated
keying of phone numbers.
– You can assign a number from the directory
to a key for quick dialling (page 35).
– You can edit or add to any phone number
selected via speed dial or from the directory
and use it for the current call.
