<strong>MGC</strong> Release Notes - Version 7.5<br />
H.239/People+Content Star Cascading<br />
Detailed Description<br />
30<br />
H.239/People+Content Star Cascading is available with mixed H.320 and H.323 Video<br />
Switching conferences.<br />
In <strong>MGC</strong> version 7.0, H.239/People+Content Star Cascading was only available in an IP<br />
Video Switching environment.<br />
All the conferences in the Star Cascading topology must have the same settings for the<br />
conference: line rate, audio algorithm, Video Parameters (Video Protocol, Video Format,<br />
Video Frame Rate, Annexes, and ProMotion) and other conferencing features such as<br />
Encryption.<br />
Highlights:<br />
• One central MCU is required in a conference. A slave MCU can only be cascaded to<br />
the main MCU. A Slave MCU cannot be cascaded with other slave MCUs.<br />
• Only two cascade options - "Master" and "Slave" - is available in H.320 H.239/ P+C<br />
cascade. There will be no "Auto" cascade mode like in regular H.320 cascade.<br />
• IVR is supported. However, if Node Type in the Participant Properties - Advanced is<br />
set to MCU, no IVR service is available.<br />
• Encryption is supported.<br />
• H.243 site names for H.320 are supported<br />
H.320 cascade links use the H.239 protocol and not <strong>Polycom</strong> P+C protocol, as in IP<br />
cascaded conferences.<br />
H.239 can only be implemented when in the system.cfg: H.239=YES.
