Microsoft Teams - Conference Calls

Microsoft Teams supports conference calls with other Teams' users using the product's Chat feature. This functionality mirrors traditional conference calls and uses wireless or wired network infrastructure (as opposed to telephone service) for communications. Microsoft Teams effectively supports up to 10 participants per conference call session and supports video and screen sharing capabilities if required.

Step by Step Guide - Hosting a Chat Call (one to one and one to many)

Once installation is completed and you are successfully logged in to Teams, follow these steps to host a conference call (one to one, or one to many) using Teams Chat feature.  This also assumes you have connected your audio headset and microphone.  If you need to test the headset audio configuration, in Teams click your profile picture in the upper right toolbar, click Settings > Devices.  Typically Teams is knows which device to adopt for call use and to validate that the settings are correct, press the "Make a Test Call" button.  If you are unable to hear audio in your headset, drop down the list of "Audio Devices" and change the selection to your audio headset brand.  Repeat the test to confirm your audio headset and microphone are selected.  This further assumes that each participant in the call has Teams installed and is logged in to the application.

Steps for one to one calls and expanding to group calls (conference calls):

  1. From the Teams menu bar on the left of the desktop application, choose "Chat."
  2. In the top center of the application, in "Search or type a command" click on the box and start typing the name of the person with whom you want to chat, or call.
  3. When the name match appears, click on it and Teams will select that contact as the person with whom you want to start a chat, or call.  Note that Teams uses stop light colors (Red, Yellow, Green) to indicate if the contact is online and available.  Teams reads your Outlook calendar and flags your presence as red (or unavailable) if you have a meeting scheduled; this does not mean you cannot participate in a call and it is an indicator of your calendar's schedule.
  4. To initiate a one to one call, press the phone handset icon in the upper right corner.  This will initiate the call and the contact for the call will receive visual and audible indicators to accept the call.
  5. Conduct the call as you would a phone call (video is optional); other in-call options are screen sharing and chat.
  6. To conference call, click on the group icon in the upper-right corner of the Teams chat window.  When clicked, Teams will prompt you to add contact names and when they match, click on the contact to add them to the call.
  7. When the call is complete, click the red icon to "hang up" or disconnect the call.
