Zoom can also be used as a conference call service. This is helpful for users who do not have smart phones or in situations where Internet access is weak but there is phone coverage.
Each Zoom meeting can be dialed into by calling 312-626-6799 and then entering the Meeting ID (which can be provided by the meeting host). Users who call in via phone can hear everyone else and can speak and everyone will hear them. The only limitations is that they will not see screens that are being shared, video, or the chat.
