ZoomCall gives you true Business Quality, Multi-Party videoconferencing over the Internet. Get crisp, full screen video with high frame speeds and crystal clear synchronous audio even at bandwidths below 128 Kbps. ZoomCall features up to 6 people in one conference, with fully mixed group audio for no annoying push-to-talk. ZoomCall also features the only software based echo suppression technology available in an Internet Videoconferencing application. Put down those earphones, and move freely in front of your camera. With on-line presence notification and dial-by e-mail, connecting with other subscribers is a snap. ZoomCall uses Visicron's proprietary wavelet based Cyclone codec to push the envelope of real time video compression and streaming technology. The Visicron Server manages user authentication, authorization, and security. The Visicron Server also allows ZoomCall to pass all firewall, network address translation, and proxies without the need for any network re-configuration.
