Homer is a free cross-platform SIP softphone with video support. The Homer software is able to communicate in peer-to-peer mode without any infra- structure. But it also supports SIP servers (PBX boxes) as well. The amount of participants per live video conferences is not limited by the software. Besides the conference functions, Homer can also be used for video/audio streaming, recording and screencasting. Video as well as audio data from files or hardware devices can be streamed to every conference participant individually. Additionally, video/audio streams can be started as separate unicast transmissions to any host in the local network or the Internet with quality settings ranging from very low to very high (HDTV). Such streams can be received by Homer and can again be recorded to disc and made available for offline playback.
