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 legacy endpoints to view Content instead of the other conference
participants.
Guidelines for Sending Content to Legacy Endpoints
• This option is enabled in MPM+ and MPMx Card Configuration Modes only.
• 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.
• Additional video resources are allocated to the conference when Content is sent to
legacy endpoints:
— In MPM+ mode, an additional SD video resource is allocated.
— In MPMx mode, an additional HD video resource is allocated.
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.
If the system cannot allocate the resource required for sending the Content, the
conference status changes to “Content Resource Deficiency” and Content will not be
sent to the legacy endpoints.
