Lync 2013 clients, connected by means of the Lync AV MCU, in point to point calls, can connect to
Collaboration Server VMR participants by escalating the Lync call to a multipoint conference,
including the Collaboration Server VMR meeting room and its participants.
The Buddy List can be used to select participants followed by, right-clicking and selecting Start a
Video Call.
An ad-hoc (Meet Now) Lync conference can be started; a drag-and-drop operation can then be
used in the Buddy List to add a Cascaded VMR to the conference.
Cascaded VMR Participants, in point to point calls, can connect to Lync AV MCU participants by
escalating the call to a multipoint Lync Conference.
A re-INVITE is issued to escalate the conference from point-to-point to multipoint.
A re-INVITE can be issued from an ongoing Audio conference to escalate it, enabling connected
participants to start sending video.
Conferences hosted on a Collaboration Server can connect in cascade to only one AV MCU hosted
conference.
The Collaboration Server can host multiple conferences, each connected in cascade to a different AV
MCU hosted conference. Conferences, connected in cascade to an AV MCU hosted conference
cannot be connected in cascade to other Collaboration Servers.
Look and Feel for Lync clients and Group Series Endpoints
Lync clients and Group Series endpoints with native Lync capability connect to the AV MCU directly and
experience a Lync look and feel conference and can see all Lync clients; up to 5 simultaneously in Gallery
View.
If the active speaker is a Cascaded VMR Participant, the participant is seen by Lync Clients in a video
window in the Gallery View.
By default, Cascaded VMR Participants are forced to a 1x1 layout by the default setting of the
FORCE_1X1_LAYOUT_ON_CASCADED_LINK_CONNECTION System Flag. The flag’s default setting is
YES, which prevents a VMR layout being displayed within a Gallery View video window. If required,
alternative Personal Layouts can be forced only after this System Flag has been added and its value set to
NO.
For more information see,
Modifying System Flags
in the Collaboration Server (RMX) Administrator’s Guide.
