Some of the above content channel features require the MCU to have been configured with the Web
conferencing feature key. The following features are only available with the Web conferencing key:

If the MCU is operating in
If the MCU is operating in
, enabling content for a conference requires the use of an
additional video port. A single video port is needed for all content channel operations, irrespective of
how many viewers there are; for example, a conference involving five video endpoints (one of which is
contributing a content stream and the other four viewing it) will require six video ports - Video ports to
reserve should be set to 5, and Content channel video set to "Enabled" in this specific example.

In reserved mode, a conference with content enabled will require a video port for content operations
even if no current participants are actively making use of content.

Note that for the MCU 4203, there are separate ports for content and for streaming viewers. For more

If the MCU is operating in
If the MCU is operating in
, enabling content for a conference does not use a video
port; instead, content uses one of the additional 'Streaming and content' ports provided by your MCU.
A single 'Streaming and content' port is needed for all content channel operations, irrespective of how
many viewers there are; for example, a conference involving five video endpoints (one of which is
contributing a content stream and the other four viewing it) will require five video ports and one
'Streaming and content' port - Video ports to reserve should be set to 5, and Content channel video

Unreserved mode
If the MCU is operating in
, enabling content for a conference works in a similar way
to streaming in that it will require a port to be allocated when content channel operations are first
attempted for that conference. For instance, this could be when a participant opens a content channel
or a user starts viewing the content channel via their web browser. When the port is no longer needed
for the conference's content channel (e.g. when the last remaining participant disconnects) the port will
be released for use by future participants or conferences.

for the conference's content channel (e.g. when the last remaining participant disconnects) the port will

Streaming
The streaming of the content channel is performed using the port allocated for content rather than the
port allocated for streaming. This means that it is possible to stream the content channel (for example,
to use the video markup feature) for conferences which do not have streaming enabled. Enabling both
streaming and content for a conference will mean that two additional ports will be required for that
conference, over and above the video and audio-only ports used by endpoints participating in that
conference.
