Initiate And Connect To A Conference - Polycom realpresence 1800 Administrator's Manual

● Either the PRESERVE_PARTY_CELL_ON_FORCE_LAYOUT System Flag = NO
or
The endpoint is not forced in the layout.
In Lync environments that do not include ICE, the empty cell will remain in the layout for direct Lync
calls.
Case 2
The RTV_MAX_BIT_RATE_FOR_FORCE_CIF_PARTICIPANT System Flag has been added to the system
with a default value of 192 (kbps). This ensures that the Lync Client sends the correct resolution and that
its cell in the Video Layout is displayed correctly.

Initiate and Connect to a Conference

There are several methods that Lync clients can use to initiate, and connect to, conferences running in an
environment that contains both Microsoft's AVMCU and Polycom's Realpresence Collaboration Servers.
This section discusses:
● Meet Now Lync Conferences
● RealConnect for Microsoft Lync (Requires DMA in the network infrastructure)
Meet Now Lync Conference
When using this method an ad hoc (Meet Now) Lync conference is started by the Lync client. A
Collaboration Server Meeting Room is then dragged and dropped into the conference from the Contact List.
This option requires that both the MCU and the AVMCU reside on the same network subnet, so that no
firewall or other barriers will trigger the NAT Traversal functionality.
To connect to an AVMCU conference:
1 Click Meet Now on the Lync menu bar, click or click the arrow next to the Options button and select
Meet Now to start an ad-hoc conference.
2 When the Group Conversation dialog box is displayed, drag the Meeting Room from the Lync
client Contacts List into the Group Conversation list.
After the Meeting Room is connected on Lync, an invitation is sent from the AVMCU to the
Collaboration Server using the Centralized Conference Control Protocol (CCCP). The Collaboration
Server responds triggering a standard SIP invite from the AVMCU to the Collaboration Server.
Multiple participants can now connect to both the Collaboration Server Meeting Room and the
AVMCU, and participate in a cascaded conference.
When a conference begins as Audio Only, a Lync user cannot add video to the conference after the
VMR is connected to the conference. The conference will remain Audio Only.
