What are diallers?
Diallers are dial-up programs that connect to an Internet or fax server via a preset tele-
phone number.
When you set up the dial-up network for connecting to your Internet provider, you have
to enter its telephone number. In principle, you are configuring a dialler whose tele-
phone number and connection charges you know.
However, there are also diallers that install themselves on your PC unnoticed and run up
extremely high connection charges. Such diallers can be concealed in a software down-
load for example, or transmit a computer virus. Such a dialler frequently has the follow-
ing properties:
u
Installation runs in the background, the dialler remains invisible during and after
installation. This makes uninstallation impossible with the normal methods.
u
The telephone number is preset and cannot be changed. The connection is made to
an expensive special telephone number or abroad.
u
The connection is made without your noticing it, making it hard to monitor the dura-
tion.
Configuring the dialler blocker
To enable the dialler blocker to protect you against unwanted connections, you must
first configure it. To do this, you need to know which connections are to be allowed and
which connections prevented. When configuring the dialler blocker, you can put
together a list of connections that are allowed. Connections you have not entered in
this list are not permitted; these connections cannot then be made.

Information for users of a DSL connection
If you use a DSL connection to connect to the Internet, you do not need
the ISDN connection provided by the Gigaset M34 USB. You can deacti-
vate the ISDN connection which will provide protection against diallers.
