VoIP – making calls via the Internet
With VoIP (Voice over Internet Protocol), your calls are not made via a fixed connection as
in the telephone network, but rather they are transmitted via the Internet in the form of
data packets.
You can take advantage of all the benefits of VoIP with your phone:
u You can make cost-effective calls in high voice quality with callers on the Internet, the
fixed line network or the mobile phone network.
u VoIP providers will give you personal numbers, with which you can be reached from the
Internet, the fixed line network and any mobile phone network.
To be able to use VoIP, you need the following:
u A broadband Internet connection (e.g. DSL) with flat rate (recommended) or volume-
based price.
u Internet access, i.e. you need a router that will connect your phone to the Internet.
You can find a list of recommended routers on the Internet at:
