Cascading
If an extremely large conference is required, sometimes the number of MCU ports available on a single MCU
is too few. In these cases it is possible to connect one MCU to another in order to create larger conferences.
This technique is called cascading and involves dialing from one MCU conference to another MCU
conference. Each MCU is seen as an additional participant on the local MCU conference. This technique
limits the experience available to participants because they can only see a large proportion of the participants
on one or another MCU.

The best user experience is always achieved by using one MCU with all participants connected to that MCU;
however, where this is not possible cascading can expand the maximum conference size.

Note: Cascading is only supported when using H.323 to call between MCUs. TelePresence Conductor can
be used to dynamically cascade MCUs as and when needed and provides a much improved administrator
and user experience compared to manually cascading.
