You have a few options to run a meeting through Zoom. Phone call only (traditional phone only) conference calling or you can do a mix of a phone and PC based conference meeting.
By default when you schedule/run a meeting with Zoom it will allow all audio Options (PC and Telephone). This will allow you to send invites that have all the methods for connecting to a Zoom meeting and let your invitee select the best solution. These meeting connections included PC video/PC audio, PC Video/Telephone Audio, PC Audio Only, or Telephone Audio only, and connecting with a Mobile device audio/video.
For a traditional phone only meeting you will need to modify the meeting when creating it with the scheduling wizard. The section you will modify is “Audio Options.” Select the “Telephone Only” Radio button to force users to Telephone only calling. Keep in mind that if you are doing a telephone only meeting you might want to edit the default invitation, remove the links, and just send the call in Telephone numbers and the meeting id.
In order to schedule this meeting you will open the Zoom Client installed on all MTAS computers. Once the client opens you will need to logon and complete the scheduling wizard. See below if you have never logged on to Zoom before.
