VoIPerized enables you to make free voice calls to other VoIPerized clients. The main focus of VoIPerized is to minimize latency, because other VoIP programs always seem 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. The program also supports conference calls and automatic port forwarding for UPnP-capable routers. Download the ZIP or RAR package and extract to a folder of your choice. Launch the program by double-clicking on VoIPerized.exe.
