Connecting an MCU Meeting Room to a Microsoft AV-MCU Conference
Microsoft Lync users can connect an MCU Meeting Room to a conference running on the
Microsoft A/V MCU. This allows MCU 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 MCU 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 MCU using the Centralized Conference Control Protocol (CCCP). The MCU
responds and triggers a standard SIP invite sent from the A/V MCU to the MCU.
Multiple participants can now connect to both the MCU 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.
