Configuring the MCU for Content Sharing via the Polycom CSS Plug-in
You can configure the MCU for content sharing via the Polycom CSS plug-in by setting the following
parameters:
● Setting the BLOCK_CONTENT_LEGACY_FOR_LYNC system flag
● Setting the Content parameters in the conference Profile
Setting the System Flag
By configuring the system flag BLOCK_CONTENT_LEGACY_FOR_LYNC you control the system
behavior in an environment where some Lync clients use the Polycom CSS plug-in and some do not. This
flag must be manually added to the system configuration to change its value.
● When set to NO (default), Content is sent to all Lync clients over the video channel, including those
with the Polycom CSS plug-in installed, even when the Send Content to Legacy Endpoints is
disabled.
Other, non-Lync legacy endpoints will not be affected by this flag and will receive content according
to the Send Content to Legacy Endpoints settings in the conference Profile.
● When set to YES, Content is not sent to Lync clients over the video channel including those with the
Polycom CSS plug-in installed, even when the Send Content to Legacy Endpoints is enabled.
Other, non-Lync legacy endpoints will not be affected by this flag and will receive content according
to the Send Content to Legacy Endpoints settings in the conference Profile.
