• An endpoint declaring SIP BFCP TCP is connected with video and audio but without
Content. The SIP BFCP TCP channel will not be connected.
• The following resolutions are supported with H.264 HD Content protocol. Only when
H.264 HD is selected, these resolutions are enabled for selection:
—HD 720p5
—HD 720p30
—HD 1080p15
• Endpoints that do not support receiving H.264 Content at a resolution of HD 720p5 or
greater are considered Legacy Endpoints and will receive Content using the people video
channel.
• Endpoints that do not support transmitting H.264 Content at a resolution of HD 720p5 or
greater are considered Legacy Endpoints and will transmit Content using the people
video channel. Depending on the endpoint type, these endpoints may not be able to
transmit Content at all - this is dependent on the endpoint and is not controlled by the
RMX.
• A mixture of older, non AS-SIP compliant and AS-SIP compliant endpoints are
supported in the same conference and are able to share Content.
• An endpoint connecting during a Content session is immediately sent an SDP Re-invite
that includes the connect media line and will receive Content.
• An endpoint connecting after Content started and was stopped will receive the SDP Re-
invite and the content media line only after a new Content request is sent.
•Once Content has been initiated by one of the endpoints, the Content channel will be
opened to all endpoints and remain open even if the Content sharing endpoint stops
sharing Content.
