What is the best Free web conferencing solution? Or best and cheapest?

You  may have a look ...

Not sure about free. DimDim may still have a free set of features, but I doubt they'll keep 'em free long. They were acquired by Salesforce. Skype is free for other Skype users and you can do a few folks conferenced in at once, I think. Plus it does video and screen sharing, so for small numbers, it's spot-on. As far as paid, I know Fuze Meeting is pretty nice. It's got a $10 by-meeting pricing, but monthly plans as well. It's web based and has VOIP/headset and Skype integration. Nice. It won't do more than 100 folks, though, so plan accordingly. And many of the larger systems (GoToMeeting is my preferred service) offer free trials.

Hello Thierry, There are several videoconferencing applications, during the last month we have integrating 6 of that (Bigbluebutton, Webex, Teleskill, Gotomeeting, Adobe Connect, Digital Samba) (As Docebo We don't have affiliation with them, we have integrated all the 6 Web Conferencing systems only through the API system). We have created a small Blog Article to explain the features of all of 6, maybe you find it useful: http://www.docebo.com/2013/04/10/use-videoconferencing-tool-docebo-elearning-platform-lms/ I hope this helps Claudio Docebo Founder & CEO http://www.docebo.com

I am currently reevaluating Go To Meeting (for cost reasons). I use Go To Webinar which works out to US$100 per month. The list I came up with 1. Cisco Webex (Too expensive) 2. Ready talk (Relatively Cheap) 3. Talk fusion (No Idea) 4. Any meeting (free) 5. Fuze meeting (No Idea) I still prefer GTM for its user friendliness.

If you really care about the user interface with some extra options, then try out ÃœberConference -->> http://www.uberconference.com/ . It offers super cool visual conference calling facility with plenty of options like call summaries, highlighting the current speaker, social integration  etc. The best part is that you can use these options for FREE.

According to me conferencecalls provides excellent web conferencing services on global network.  Their web conferencing services is very cost effective and provides organisations to get high quality videos on web conferencing. However, every organisation has different needs when it comes to web conferencing and what might be ideal for one organisation is not necessarily need to be  ideal for another organisation .

Yuuguu (http://www.yuuguu.com) offers a free seven day trial and then a low-cost version (works out at less than $10 pcm).  Yuuguu is simple to use, cross platform and only the host of the session needs to install anything.

Google Hangouts? They also have a enterprise version (not free though). http://www.google.com/enterprise/apps/business/landing/plus/features.html
