Abstract: An audio conference of three or more communication devices is set up. An audio stream of at least one of the communication devices is identified as having an audio signal that is disruptive of the audio conference. For example, a disruption to the audio conference can be where a user has placed the audio conference on hold with music-on-hold, typing without talking, the user is speaking too loudly, the user is speaking too softly, there is echo, there is a bad connection, and the like. A feedback message is sent to the communication device associated with the audio stream with the disruptive signal. The feedback message can cause the user of the communication device who is disrupting the audio conference to take action without disrupting other participants in the audio conference.
