What differences do I see when muting/unmuting meeting controls in dual homed conferences in version 2.4?

Meeting Server version 2.4 introduced improved mute/unmute meeting controls in dual homed meetings for:

  • on-premise and Office 365 Skype clients,
  • end point users,
  • Meeting App users.

Here Lync and Skype for Business clients are generically referred to as Skype clients.
It is assumed that muting/unmuting is enabled using the API of the Meeting Server.

  • Skype clients can mute and unmute anyone in the dual homed conference, this means themselves and others, and they can mute and unmute the audience too.
  • Skype clients can mute self, unmute self, and also mute audience and unmute audience which will affect other Skype clients and endpoints in dual homed conferences.
  • All endpoint users can now mute Skype clients.
  • Endpoint users on the Skype side of the AVMCU can now mute and unmute themselves (self) and other endpoints (either on the Skype clients/endpoints of the AVMCU or on the Meeting Server side). Prior to version 2.4, only endpoint users on the Meeting Server side of the AVMCU could mute and unmute themselves (self) and others. 
    • For non-ActiveControl endpoints, the Meeting Server sends DTMF key sequences for each mute and unmute, and overlays an icon on the media stream to the endpoint to indicate whether the endpoint is muted or unmuted.
    • For ActiveControl endpoints running CE 9.2.1or later software, the endpoint handles the icons and messages (the Meeting Server does not overlay icons).
  • Once an ActiveControl endpoint is muted it has to be unmuted locally so as to ensure the privacy of any local conversation. For example, when a remote participant mutes an ActiveControl endpoint and then tries to unmute it, the ActiveControl endpoint will mute itself again until it is locally unmuted.
  • When a remote participant tries to unmute a non-ActiveControl endpoint, the non-ActiveControl endpoint will be unmuted.
  • Meeting App users and Cisco Meeting Management users can mute and unmute Skype clients. They also see the correct mute state of all participants in the meeting.
Muting/unmuting Meeting App users:
  • Information on local muting and unmuting of a Meeting App user is not passed to Skype clients in dual homed conferences. However, if a Skype client remotely mutes a Meeting App user and the Meeting App unmutes itself, the Meeting Server tells the Skype client about the unmuting.
  • When a remote participant tries to unmute a Meeting App user, the Meeting App user will remain locally muted. Note: other participants will still see them as unmuted, although they are actually muted.
  • The Meeting App shows the mute/unmute state using its own icons. Meeting Server icons are not overlaid on the Meeting App video pane.
