Sending Content to Legacy Endpoints in Telepresence Conferences
The RMX can be configured to manage the layouts of to H.323/SIP/ISDN endpoints that do
not support H.239 Content (legacy endpoints) over the video (people) channel in
Telepresence conferences when Content is being sent. This feature is controlled using the
FORCE_LEGACY_EP_CONTENT _LAYOUT_ON_TELEPRESENCE flag. This flag must be
added to change the value.
The values of the flag are:
•
NO (Default) - The MCU does not manage the layouts while Content is sent. Personal
layout changes, for example, by MLA, override the default MCU layout. Legacy
endpoints may not display Content in Telepresence conferences due to layout changes.
• YES - The MCU manages the layouts while Content is sent. Personal layout changes, for
example, by MLA, are ignored. The layouts for legacy endpoints are managed by the
MCU.
Guidelines for Sending Content to Legacy Endpoints in Telepresence
Conferences
• MLA layout change requests for legacy endpoints will be ignored until Content is
stopped. At that point, MLA can be used again.
• Click&View can not be used to change the layout while Content is being sent.
• The Polycom Touch Control can not be used to change the layout while Content is being
sent.
Content Display on Legacy Endpoints in Telepresence Conferences
When Content is sent to legacy endpoints in Telepresence conferences, their video layout
automatically changes to a “Content layout” which is defined by the system flag
LEGACY_EP_CONTENT_DEFAULT_LAYOUT. If MLA is managing the Telepresnce
layout prior to Content being sent, the MCU takes over managing the layout of Legacy
endpoints once Content is started. The video layouts of the other conference participants
continue to be managed by MLA.
When Telepresence Mode is enabled, the Skins options are disabled as the system uses a black
background and the frames and speaker indication are disabled.
