Sending Content to Legacy Endpoints
The RMX can be configured to send Content to H.323/SIP/ISDN
endpoints that do not support H.239 Content (legacy endpoints) over the
video (people) channel, allowing the participants using the legacy
endpoints to view the Content as the other conference participants.

Guidelines for Sending Content to Legacy Endpoints

• This option is enabled only in MPM+ Card Configuration Mode and
Resource Allocation Mode is set to Flexible Mode.
• This option is valid when sending Content as a separate stream is
enabled in the System Configuration and the flag: ENABLE_H239 is set
to YES.
• One additional SD (3CIF) video resource is allocated to the
conference when Content is sent to legacy endpoints. The allocation
is done only when a legacy endpoint is connected to the conference
and a Content session is initiated and transmitted via the video
channel.
Once the resource is allocated, it remains allocated to the conference
until the conference ends.
Content
Protocol
H.263 – Content is shared using H.263 even if some
endpoints have H.264 capability.
Up to H.264 – H.264 is the default Content sharing
algorithm.
When selected:
•Content is shared using H.264 if all endpoints have
H.264 capability.
•Content is shared using H.263 if all endpoints do not
have H.264 capability.
•Endpoints that do not have at least H.263 capability
can connect to the conference but cannot share
Content.
