Connecting a Collaboration Server Meeting Room to a Microsoft AV-MCU
Conference
Microsoft Lync users can connect an Collaboration Server Meeting Room to a conference
running on the Microsoft A/V MCU. This allows Collaboration Server Lync users to connect
with a conference in progress on the A/V MCU and be an active participant in the
conference. The connection to the A/V MCU is the same configuration as a cascading
conference between multiple Collaboration Server MCUs.
To connect to an A/V MCU conference:
1 From the Menu bar, click Meet Now to create an ad-hoc conference.
The Group Conversation dialog box is displayed.
2 From the Contacts List on Lync, drag a Virtual Meeting Room (VMR) into the Group
Conversation list.
After the Virtual Meeting Room is connected on Lync, an invitation is sent from the A/V
MCU to the Collaboration Server using the Centralized Conference Control Protocol
(CCCP). The Collaboration Server responds and triggers a standard SIP invite sent from the
A/V MCU to the Collaboration Server.
Multiple participants can now connect to both the Collaboration Server Meeting Room and
the A/V MCU, and participate in a cascaded conference.
When a conference begins with Audio Only, a Lync user cannot add video to the conference after
the VMR is connected to the conference. The conference will remain as Audio Only.
