You probably clicked on this site because you saw the phrase "Free Video Conference" somewhere in the title or description of the page. In our minds nothing beats free, especially if you don't mind the quality of whatever, you are getting for free is not as up to date as the others.
When I say others, I mean "up to date" or as advanced as the products or services that are offered by companies like Tandberg, PicturePhone, etc.
In order to use these free programs you can download them on your laptop or personal computer.
Also, you can (which is what most video conferencing users do) use a browser based program.
This is especially popular among those who enjoy life working at home when they have an MLM business or people who are retired and choose to be self employed.
Again, what this means is that you can just go to your laptop or personal computer and type in the video conferencing website address. Login with your webcam and microphone, click on a person's profile and begin chatting. A webcam and microphone are necessary if not mandatory to have a successful video conferencing session.
Of course, just because these services are free doesn't mean it's cheap quality. Many businesses use free video conference programs to communicate with business partners. However, there are many features that don't come with these free programs. Features such as telepresence capabilities, whiteboarding, etc.
If you want these features then most likely you would have to pay for it.
The free video conference programs that are available for use today are:

It is important to realize while these programs are here for you, all of them might not have all the features you need. Due diligence is needed to make sure you get what you are looking for.
