Multipoint Calls Using Centralized Conferencing Control Protocol
(CCCP)
If a Polycom RealPresence Group system is deployed in a Microsoft Lync Server 2010 or 2013 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. If you are used to being in conferences
hosted by a Lync server, you might notice that the Polycom RealPresence system interface closely
resembles the interface you see in Microsoft environments.
For more information about CCCP multipoint calling, refer to the Polycom Unified Communications
Deployment Guide for Microsoft Environments or contact your system administrator.
To manually create a multipoint call with CCCP:
1 From the Call screen on the Polycom Touch Control, touch Conference.
2 Create a list of participants you want in the call. You can add participants using any combination of
the following methods.
Touch Keypad, then enter SIP addresses. Each time you enter a SIP address, touch Add to add
it to the list of participants.
Touch Directory, then touch the names you want to include in the list of participants. If you touch
a group, the group opens and you can touch the individual names to add them.
Touch Favorites, then touch the names you want to include in the list of participants.
3 To initiate the conference call, touch Join when your list of participants is complete.
After you touch Join, you can touch Add Participant to add other participants as described in step
2 without putting other participants on hold, although you might experience a brief audio or video
pause.
To add participants to a CCCP conference using the Polycom Touch Control:
1 From the Call screen, touch Add Participant.
2 Select Keypad and enter a number to call, or choose a site from one of the following locations:

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 RealPresence Group system selectively, you can unmute your system
Polycom RealPresence Group systems do not support Office Communicator or
Microsoft Lync distribution list groups, which are created on the Microsoft Exchange
Server and are typically used for sending email to a group of people.
