Conference calls allow multiple people to participate in meetings over the phone, reducing travel costs and improving efficiency. They require planning meetings in advance, keeping people on track, and committing to the call. Skype offers free conference calling via computer and requires only an internet connection, microphone, speakers, and optionally a webcam. Users must create accounts, search for contacts, and purchase Skype credit to call regular phone lines. Videoconferencing allows seeing and hearing contacts but requires sufficient computer performance.
