Forcing Other Content Capabilities
The H239_FORCE_CAPABILITIES system flag in system.cfg gives additional control over Content
sharing:
When the flag is set to NO (default), the Collaboration Server only verifies that the endpoint supports
the content protocols: H.263 or H.264.
When set to YES, the Collaboration Server checks frame rate, bit rate, resolution, annexes and all
other parameters of the Content mode as declared by an endpoint during the capabilities negotiation
phase. If the endpoint does not support the Content capabilities of the MCU, the participant will not
be able to send or receive content over a dedicated content channel.
Content Sharing via the Polycom CCS Plug-in for Microsoft Lync Clients
From version 8.1, Polycom CCS (Content Collaboration Solution) Plug-in for Lync clients allows Lync clients
to receive and send Content on a separate channel, without having to use the video channel. Content is
transmitted using SIP BFCP.
