What video conferencing software is available? [closed]

Skype:

You can use Skype, which fully supports video conferencing and other useful features, such as screen sharing. http://www.skype.com/download

aMSN

Even when aMSN is able to perform video conferencing, recently it is a difficult task as there are several changes in the MSN services and the way that it handles video connections.

In aMSN is it that easy as having installed Farsight, which is automatically installed in the majority of the cases and if not you will have enough information and a guide in order to install it.

Anyway it may fail as I have said in my initial words.

Web Services

You may wish to give a chance to an online free video conference service, such as

Ubiqq http://ubiqq.com

Ubiqq uses a flash player based interface in order to gain access to both your webcam and microphone and allows the same in your contact's side.

A whole thread about how to make these online services to work is fully documented right here. Just in case that you can't make it work out of the box.

Good luck!

OpenMeeting

OpenMeetings is a free browser-based software that allows you to set up instantly a conference in the Web. You can use your microphone or webcam, share documents on a white board, share your screen or record meetings. It is available as hosted service or you download and install a package on your server with no limitations in usage or users.

Google hangouts offers screen sharing and group meetings (unlike skype which you have to pay for groups). Everything is supported within the browser so very easy to install and collaborate with users of various OS and technical savvy.
