Content Sharing via Polycom® ContentConnect™ Plug-in for Microsoft Lync Clients
From version 8.1, Polycom® ContentConnect™ (Content Sharing Suite) plug-in for Lync clients allows Lync
clients to receive and send content via SIP BFCP, without having to use the people video layout.
The Polycom® ContentConnect™ plug-in invokes a separate call for content with or without video. This call
may be invoked per a Lync client.
Microsoft Lync is not supported by Collaboration Server (RMX) 1800 with no DSP cards.
Dial-in / Dial-out Connections
For dial-out and dial-in connections to and from SIP Clients, BFCP/UDP or BFCP/TCP protocol can be given
priority by adding the adding the SIP_BFCP_DIAL_OUT_MODE and SIP_BFCP_DIAL_IN_MODE System
Flag to system.cfg and setting their values to UDP, TCP or AUTO.
The Collaboration Server's content sharing, as determined by the system flags settings and SIP client
capabilities, is summarized in the following table:
System Flags - SIP_BFCP_DIAL_OUT_MODE / SIP_BFCP_DIAL_IN_MODE
Flag Value
AUTO (Default) BFCP/UDP selected as
content sharing protocol
UDP
TCP Cannot share content
BFCP support in dial-in Connections
● The MCU shares content with dial-in SIP clients according to their preferred BFCP protocol.
● SIP clients connected as audio-only cannot share content.

Content Sharing Using People+Content Protocol

People+Content utilizes a different content control protocol, and is Polycom's proprietary protocol used prior
to H.239. This protocol is supported in CP conferences, and is applicable for H.323 and ISDN endpoints.
Guidelines for Content Sharing Using People+Content Protocol
● If an endpoint supports both H.239 and People+Content protocols, H.239 is selected as the preferred
communication protocol.
● H.263 and H.263 and H.264 Auto-selection are the only supported content media protocols usage
modes (see MCU Usage Modes of Content
● People+Content is enabled by default. It can be disabled for all conferences and endpoints by
manually adding the ENABLE_EPC System Flag, and setting its value to NO (default value is YES).
