Internet Telephony: development of a demonstrator for voice over IP

Abstract [en]

In today’s society the ability to connect to the Internet via high-speed connections is spreading rapidly, and the need for good transmission of sound in different applications becomes more and more important. One possible application is to make telephone calls over the Internet. This technique is called Voice over IP and is a relatively new area. Our thesis work aimed at creating a demonstrator for this technique, at first on a PC and as a second goal on a target processor with associated hardware. At first an investigation of what this technique really meant was performed and reflected upon. Then a lot of programming was done to implement the standard for how to do this kind of phone calls. We decided to use the Session Initiation Protocol (SIP) and Session Description Protocol (SDP) to set up a conversation and actual speech data is transmitted with the Real-time Transfer Protocol. These protocols were chosen based on what the market is using, these standards seem to be up and coming. We got it operating and demonstrated the functionality on PC-level and on a possible alternative for a processor in late November.
