Facilitators/hosts should be able to join audio via "Computer Audio." If the facilitator/host experiences challenges with the audio breaking up or a delay in audio when speaking to attendees, the facilitator should rejoin the audio via their phone line.  Locate the Join Audio menu bar at the left of the menu bar (this menu bar may be next to the "Mute" button if you have already joined audio), and select the "Call Me" option to ensure your audio remains connected in the event that your WiFi fails. This way, you will remain connected via audio withe the attendees.
