Iotum today launched Calliflower, their free conference call service integrated into a web app. The app has dial-in numbers for the USA and France, but also notably allows callers to connect up via a free Truphone VoIP plug-in, and also a free Sitofono plug-in. At a glance, you can see pictures of all of the attendees to the call, and see their status (muted, hand up etc) and there is also a “live wall” feature; a back-channel that allows a shared IM chat to go on between attendees at the same time as the call.
