Answer for What video conferencing solutions can you recommend for schools?

Citrix Gotomeeting has been used in some school I know as well as Skype. However, my current favourite is BlueJeans, http://www.bluejeans.com
The BlueJeans solution offers video and audio conferencing from Windows computers and Macs as well as iPads, iPhones and android and if you dont have a computer or smart phone then you can dial into a meeting using a typical telephone for audio only conferencing.
Another advantage that BlueJeans offers is its ability to integrate into room conferencing systems such as the TelyHD which is useful when you have a room full of participants.
