When you are choosing to set up your conference call, there are a number of options that you have. The accessibility of video conferencing has grown significantly over recent years, and with the advent of computer tools such as the webcam then it is a medium which is much more realistic than it once was.
The most obvious benefit of all when you are hosting a video conference is that you can actually see the faces of the people you are speaking with. This will make it much easier if you are seeing if somebody wishes to speak, and can avoid the messy speaking over one another which can happen in a badly controlled voice conference call. The video conference also can give you more of an understanding of what the speaker is saying at all times, as you can read the body language and facial expressions of those who are speaking. You can also have a better gauge of what you are saying is being received, as you see those you are speaking to.
However, the video conference tends to be particularly successful when it is a small number of participants that are taking part, as the more people involved, then the smaller their faces will become on the screen on which you are watching the other participants. Also, by adding an extra layer of technology to the conference, it becomes more likely that someone may experience some technical problems, as webcam technology is not yet infallible.
