Making Telephone Calls via the Internet
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.
