VoIPerized is a so called VoIP (Voice over IP) program. VoIPerized enables you to make free audio calls to other people who also run VoIPerized. When making VoIPerized the focus was to minimize the latency, because other VoIP programs always seemed to have an irritating lag which makes the conversation seem unnatural. By using the open source Speex audio codec the audio quality is far higher than any normal telephone call.
