I developed this IP telephony concept during the autumn 2000 for Ericsson Business Corporation. The work included doing the interaction design, graphical design, prototype development and usability testing. This was three years before the first version of Skype was launched 2003. The sound quality in the application was incredible good at the time. This at a time when most people used dialup modem to access internet and hardly anyone used a wireless access. Laptops was rare, and about 90+ % of the population in the developed world still had fixed line phones at home. In Sweden at that time about 40% of the population used internet at work at least on a weekly basis.
