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 net-
work) or via the Internet (VoIP). You decide which connection you want to use
for a specific call when you dial the number. You have the following options:
u Select the connection type with the Talk key c (briefly press/press and
hold c), £
Page 45.
u Select the connection type via the Display keys by assigning VoIP and/or the
fixed line network to your Display key, £
Page 46
u Select a special connection via your line suffix, £ Page 47
Use the Talk key to select the type of connection and make the call
By briefly pressing or pressing and holding the Talk key c, you can determine
the type of connection for the call you want to make (fixed line network or
VoIP).
Prerequisite: You enter the number without a line suffix (
£
Page 47) and
have not defined any dialing plans for this number.
~c Enter number (without suffix) and briefly press/press and hold
the Talk key.
Please note
u You can conduct three separate external calls via your base station (using
different handsets): two calls via VoIP and one via the fixed line network.
u During an external call, you can see from the color scheme of the display
whether you are connected to the other party via VoIP or the fixed line net-
work. When you make or receive a call on the fixed line network, the display
color changes to orange.
u You can define dialing plans for certain numbers or area codes by determin-
ing the connection and therefore the billing method to be used (cost control
£
Page 172) when these numbers are dialed.
u Dialing with the Directory (£
Page 70), Quick dial (£ Page 124) or Last
Number Redial list (£
Page 65) saves repeated keying of phone numbers.
You can modify or add to these numbers on a call by call basis.
u If you use VoIP to make a call to the fixed line network, you may also have
to dial your local 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 con-
figuration (
££
Page 135, Page 171) and activating the option Predial
area code for local calls through VoIP
(£
Page 171).
u Depending on the exchange, you may not have to dial your own area code
when making local calls via the fixed line network.
