Ring2 specializes in phone- and web-based conferencing, recently bundled with medical services for BlackBerry. Their mobile solution allows users to participate in and control phone conferences from anywhere. Using a BlackBerry, you can be instantly notified when someone joins a conference and see a list of all participants. If you don’t recognize a name, you can drop them from the conference entirely or place them on hold, and even mute users if background noise interferes with the call. Finally, you can save the entire conference to MP3 for later retrieval. Hopefully we’ll get to see some new features at their booth at WES.
