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.
Conference Profile Settings
Content is shared in a video switching mode. Therefore, when a Lync client connects to the conference via
the Polycom CSS plug-in, the content resolution will be adjusted to the maximum content rate possible by
the Lync client, up to a maximum of 720p 5fps in all line rates, even if you select a higher content rate and
resolution in the Conference Profile.
