If you are in a room with several people and multiple audio devices, you might hear a screeching sound or echo on the audio call.


Try the following:

  • Mute your microphone and speakers, or request others in the room to mute their audio.
  • If several people in the same room want to join the same call, consider using a device with a speakerphone, or have participants mute their microphones whenever they are not speaking.
