Making calls with VoIP and the fixed line network

Making an external call

External calls are calls made via the public telephone network (fixed line network) or via

the Internet (VoIP). You generally decide which connection type you want to use for a spe-

cific call when you dial the number.

Use the talk key to select the type of connection and make the call

By briefly pressing or pressing and holding the call key

c, you can determine the type of

connection for the call you want to make (fixed line network or VoIP).
Precondition: You enter the number without a line suffix (page 32) and have not defined

any dialling plans for this number.
~ c

Enter number (without suffix) and briefly press/press and hold the talk key.

A default connection is established on your phone (fixed line network or VoIP, page 117/

page 144).

¤

Briefly press the talk key

c if you want to make a call via this default connection.

¤

Press and hold the talk key

c if you want to make the call via the other connection

type.

If you have assigned a number of VoIP numbers to your phone, you can define which VoIP

number (VoIP account) is used for external calls from each specific handset (handset send

number, page 144).

Please note:

– You can conduct up to three separate external calls via your base station (using different hand-

sets): two calls via VoIP and one via the fixed line network.

– You can define dialling plans for certain numbers or area codes by determining the connection

and therefore the billing method to be used (cost control, see page 149) when these numbers are

dialled.

– Dialling with the directory (page 49), quick dial keys (page 109) or last number redial list

(page 56) saves repeated keying of phone numbers. You can modify or add to these numbers on

a call-to-call basis.

– If you use VoIP to make a call to the fixed line network, you may also have to dial the area code for

local calls (depending on the VoIP provider). You can avoid having to dial your own area code by

entering it into the configuration (page 148). Your area code is then added automatically when

you make local calls.

Please note:

If you are using a GAP compatible handset other than the Gigaset handsets C47H, S67H, S68H,

SL37H, S45 and C45, every call will be made via the standard connection, even if you press and hold

the call key. If you want to use the non-default connection to make a call, enter a star (*) at the end

of the number.
