● An ongoing audio conference is escalate to video, enabling connected participants to send video.
● Multiple Collaboration Server conferences cannot be cascaded into the same Lync 2013 AVMCU
conference. Multiple concurrent cascades are supported in a 1:1 fashion between simultaneous,
separate conferences.
● The Collaboration Server can host multiple conferences, each connected in cascade to a different
AVMCU hosted conference.
Look and Feel for Lync Clients and Group Series Endpoints
Lync clients and Group Series endpoints with native Lync capability connect to the AVMCU 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.

Look and Feel for Legacy Endpoints

simultaneously in Polycom video layouts. Only Classic Skin is supported. For more information about Skins,
