Frequently Asked Questions - How do I determine whether participants in the meeting were muted by a Lync or Skype for Business client user?

Use GET on /calls/<call ID> to retrieve the lyncAudienceMute parameter. If the parameter is set to:

true then the participants were muted by a Lync or Skype for Business client user

false then the participants were not muted by a Lync or Skype for Business client user

The lyncAudienceMute parameter is only present if this call is a Skype/Lync conference.
