4.3 Useful Tips for Internet Telephony
with FRITZ!Box Fon
Making Telephone Calls via the Internet
All kinds of data transmission in the Internet use the Internet
Protocol (IP). IP is packet-oriented. That means that a set of
data to be transmitted is decomposed into a number of data
packets, and IP provides for the transport of the individual
packets through the Internet. Language is also transmitted in
the Internet in this manner.
In opposition to this, fixed-line telephony transmits data in a
line-oriented manner. In this case data are transmitted in a
coherent data stream.
For packet-oriented transmission in the Internet, the loss of
packets cannot be ruled out completely. Under unfavorable
conditions this can lead to speech quality in Internet tele-
phony that is inferior to that in fixed-line telephony.
Clearing Internet Connections Automatically
If you use FRITZ!Box Fon for Internet telephony, disable the
“Clear Internet connection automatically” option in the
“ Internet / Account Information” menu to prevent a
connection from being cleared during a call over the Internet.
For more information about the “Clear Internet connection
automatically” function, see the Online Help of the FRITZ!Box
Fon user interface.
