Internet telephony with KPhone
Internet telephony does not need to be complicated. You can talk to the world with just Kphone, a normal sound card, and an account with an Internet phone provider.
KDE’s Kphone program, which Suse Linux and other distributions have recently started to include, is a simple telephony application for Linux. Kphone serves as a handy desktop tool for Voice over IP connections. You'll find that Kphone is very easy to configure. As you can see in Figure 1, the program prompts you for a few details when you launch it: in fact, you only need to specify the User Part of SIP URL and the Host Part of SIP URL. The Outbound Proxy is only required for extremely restrictive firewalls to allow outgoing connections. To be on the safe side, you might like to specify the proxy server for your first experiments, but try to do without a proxy later.
