Furthermore, Audio conferencing does not work very well for complex communication techniques, such as those used in closing a sales contract. Audio Conferencing offers a meeting rather impersonal, and socialization and the binding does not occur as they would in the real world. You can configure audio and Video conference in a number of different ways. The oldest method, using a variety even thinner is to have a group in one room, another group in another room (perhaps in another city or country) and have them talk to each others. Each of the two groups using a television, a video camera mounted on a television, a speaker, and perhaps some file sharing software for collaboration on projects.
