Cisco Cisco TelePresence MCU 4510 Maintenance Manual
Changing the Owner of a Conference
A user whose privilege level is either conference creation and full control or administrator is also able to change the
owner of a conference. A conference owner can be changed to either a user with conference creation rights or to
"none", signifying that no user should be considered the owner of that conference. Also, when scheduling new
conferences, users with these privileges are able to choose which owner is initially associated with the conference.

Deleting Users who are Conference Owners
If a user account is deleted, any conferences owned by that user have their owner reset to "none".

Reservation of MCU Media Ports
The MCU is able, if required, to allocate its available media ports in advance to specific conferences. This means that
it is able to guarantee that a certain number of participants will be able to join that conference, irrespective of how
many other people are using the MCU for other conferences at the same time.

Media Port Types
There following types of media port are available on the MCU:
■
video ports
■
audio-only ports
■
streaming and content channel ports
For information about the number and type of ports provided by each MCU model, refer to
The term video port refers to a port that can be used by a video-conferencing endpoint for a call. Thus, a video port
includes both video and audio streams (bidirectionally) and so the number of video ports available represents the
number of "normal" video calls that the MCU is able to maintain simultaneously.

Participant Port Usage
In general, each endpoint in a conference is able to use either a video port or an audio-only port, though normally the
MCU will assign video ports to video-capable devices and audio-only ports to audio-only devices.
MCU will assign video ports to video-capable devices and audio-only ports to audio-only devices.
If a video-capable device joins a conference which only has audio-only ports available, the MCU will assign it an
audio-only port - that participant will be able to listen to other people and contribute their own audio to the
conference but the MCU will not transmit video to it (and will not use any video received from it). If an audio-only
device such as a simple telephone joins a conference which has just video ports available, the MCU will assign it a
video port, which includes audio capability. The video capability of that allocation will not be used, but the audio
device will be able to participate as normal in the conference. The exception to this is VNC - because this is a video-
only protocol, the MCU does not permit VNC connections to use audio-only ports.

Streaming
Streaming a conference requires use of a video port or a streaming and content channel port. Where streaming and
content channel ports are provided, streaming viewers and conferences' content channel (H.239 or BFCP) video
allocations will use the streaming and content channel ports rather than the available video ports; where streaming
and content channel ports are not provided, streaming viewers and content channel allocations will use available
video ports.
