48 FRITZ!Box Fon WLAN 7050 – 4 Making Calls with FRITZ!Box Fon WLAN 7050
If you would like to use a certain kind of connection (Internet
or fixed-line) for a call, dial the following keys on the tele-
phone keypad before the number:
Fixed-line Connections
s111r
establishes a fixed-line connection
Internet Connections
s12r
establishes an Internet connection. The Internet
number used is the Internet number set for line 1
s12 P r
establishes an Internet connection for a selected
Internet number. For "P", enter the position of the
Internet number in the "List of Internet Numbers".
All kinds of data transmission in the Internet use the Internet
Protocol (IP). IP is packet-oriented. This means that the data
are broken down into data packets for transmission and IP
takes care of the transport of the individual data packets
through the Internet. Language is also transmitted in the In-
ternet 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.
