Setting Up a Cascaded Conference
The following are prerequisites for a cascaded conference:
Each individual conference must have the same or similar
video bit rates and frame rates.
Prefixes of conferences provided by the MCU must be
unique.
All MCUs participating in the cascaded conference must
register with the same gatekeeper or neighbor gatekeeper.
To create a cascaded conference, you must invite a MCU to join a
conference managed by another MCU. If a participant joins a conference
on the invited MCU, it actually joins the cascaded conference, and can
exchange voice and video as usual. There are two methods of inviting a
MCU to join a conference:
By using the MCU monitoring screens through a Web
browser.
By using a terminal to invite an MCU to join when dialing
into a conference.
To invite a MCU to join a conference using a terminal such as an IP
phone, dial the conference password of the host MCU, the invite string
**, then the conference password of the invited MCU.
For example, to invite a MCU whose conference password is 828 to
join a conference hosted by a MCU with the password 007, dial
007**828. Other MCUs may then be invited into the conference by terminals
connected to the cascaded conference.
