TokBox launched about two years ago and got good coverage on TechCrunch. It has turned out to be a great free (and hassle-free) video conferencing tool. I'm on the phone with clients and candidates all day... hey, it's a people business! It helps a lot when you can see who you are speaking with. So, I'm using it from time to time.
It used to be that you had to have the special video conferencing gear (or now the "Telepresence" gear from folks like Cisco, Polycom, Tandberg and others). The quality of the new HD systems is phenomenal. But for a small business such as ours, I don't need HD.
With TokBox, all you really need is two webcam equipped PC's. I'm also a big fan of Skype... but not everyone is a Skype user. That's what makes TokBox so handy. I can just give people my personalized ToxBox url when I want to get into a video conference with them and that's it. No installs, no hassles (TokBox is all Flash based), no cost.
And for the social networkers out there... TokBox integrates nicely with all of the key sites like Facebook, Twitter, etc.
I've been using FreeConference for the last couple of years. The service has been very reliable. The teleconferencing service is free. You only pay for the long distance call. But since I subscribe to an unlimited calling plan, the whole things comes at no charge.
The access number is +1-218-844-3366. You then enter a unique 6 digit access code (any 6 digit code will do). Just make up any 6 digit code and give this "access code" to everyone that you invite to the call.
While you are on the call, you can enter a number of touch-tone commands as shown below:
