In order to avoid cluttering in the cascaded window, it is advised to select
appropriate video layouts in each conference before cascading them.

The following features are not supported by the cascaded link and
therefore are not supported in the combined conference:
• DTMF codes are enabled in cascaded conference, but only in their
local conference. The operations executed via DTMF codes are not
forwarded between linked conferences.
• H.239 (Content channels will only broadcast in their local MCU).
• FECC (Far End Camera Control will only apply to conferences
running in their local MCU).
