Multipoint Calls Using Centralized Conferencing Control
Protocol (CCCP)
If a Polycom HDX system is deployed in a Microsoft Lync Server 2010
environment and Centralized Conferencing Control Protocol (CCCP) is
enabled, you can place and participate in multipoint calls that are hosted by
Microsoft audio and video servers.
Contact your system administrator and the Polycom Unified Communications
Deployment Guide for Microsoft Environments for more information about CCCP
multipoint calling, which is referred to as Lync Conferencing in that book.
Muting in a CCCP Call
A Microsoft Lync client acting as the call organizer can mute all of the
participants in the call. You cannot unmute until the organizer unmutes the
participants unless you are designated as a presenter. If the meeting organizer
has muted your Polycom HDX system selectively, you can unmute your
system even if the organizer does not. It is important to understand that no one
else can unmute your microphone. They can only request that you unmute.
When your mute status changes due to a Microsoft Lync client organizer
muting or unmuting all of the participants, notification is displayed on the
Polycom HDX system monitor.
Available Indicates that the HDX system or
Office Communicator or Microsoft Lync
user is available.
Offline Indicates the HDX system or Office
Communicator or Microsoft Lync user
is offline.
Presence Unknown Indicates that the presence state of the
HDX system or Office Communicator
or Microsoft Lync user is unknown.
