Issue   You are in a room with several people and multiple audio devices, and you hear a screeching sound or echo on the Microsoft Lync 2010 call.

Resolution   Mute your microphone and speakers, or ask others in the room to mute their audio. If several people in the same room want to join the same Lync 2010 call, consider using a device with a speakerphone, or have participants mute their microphones whenever they are not speaking.
