What is Integrated Digital Services Network (ISDN)

Videoconferencing (VC) is primarily a synchronous, long distance, e-collaboration tool. Although it offers interpersonal features with some degree of media richness and social presence, it is not a perfect substitute for face-to-face communication. VC can add value in business situations where telephone, text chat, or audio conferencing do not provide adequate secondary communication channels such as nonverbal cues (tone of voice, inflection) and interactions (body language). VC also adds value where it is impossible or undesirable to conduct a personal meeting. Currently there exists an opportunity for organizations and individuals to derive enormous benefit from this medium when used appropriately with necessary tactics and skills, especially when multiple parties are involved in e-collaboration.
