VoIP – making calls via the Internet
With VoIP (Voice over Internet Protocol), your calls are not made via a fixed con-
nection as with 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 cell 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 cell phone net-
work.
To use VoIP, you need:
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:
