Homer – Free SIP Softphone that Supports Video Conferencing

Homer is a free cross-platform SIP softphone, which also supports video conferencing. Both video and audio streams of conference participants can be captured. The amount of simultaneous participants for live video/audio chats is unlimited by the software. Video as well as audio files can be streamed during a conference session.

Homer supports low quality as well as high quality audio and video streams depending on the program settings. It can also be used to stream a live view of the current desktop screen. Homer communicates peer-to-peer but SIP servers (PBX boxes) are supported as well.
